tests: bulk changes to avoid whitespace errors of check-code.py

This is a part of preparation to apply checking with check-code.py on
code fragments embedded in *.t test scripts.

This revision avoids "whitespace" errors of check-code.py below:

  - missing whitespace after ","
  - missing whitespace in expression
  - no whitespace around "=" for named parameters
  - wrong whitespace around "="

 convert fresh repo and also check localtimezone option
 
 NOTE: This doesn't check all time zones -- it merely determines that
 the configuration option is taking effect.
 
 An arbitrary (U.S.) time zone is used here.  TZ=US/Hawaii is selected
 since it does not use DST (unlike other U.S. time zones) and is always
 a fixed difference from UTC.
 
 This choice is limited to work on Linux environments. At least on
 FreeBSD 11 this timezone is not known. A better choice is
 TZ=Pacific/Johnston. On Linux "US/Hawaii" is just a symlink to this
 name and also it is known on FreeBSD and on Solaris.

 Test transcoding CVS log messages (issue5597)
 =============================================
 
 To emulate commit messages in (non-ascii) multiple encodings portably,
 this test scenario writes CVS history file (*,v file) directly via
 python code.
 
 Commit messages of version 1.2 - 1.4 use u3042 in 3 encodings below.

 Examine whether module loading is delayed until actual referring, even
 though module is imported with "absolute_import" feature.
 
 Files below in each packages are used for described purpose:
 
 - "called": examine whether "from MODULE import ATTR" works correctly
 - "unused": examine whether loading is delayed correctly
 - "used":   examine whether "from PACKAGE import MODULE" works correctly
 
 Package hierarchy is needed to examine whether demand importing works
 as expected for "from SUB.PACK.AGE import MODULE".

 Asking for help about a deprecated extension should do something useful:
 
   $ hg help glog
   'glog' is provided by the following extension:
   
       graphlog      command to view revision graphs from a shell (DEPRECATED)
   
   (use 'hg help extensions' for information on enabling extensions)
 
 Extension module help vs command help:
 
   $ echo 'extdiff =' >> $HGRCPATH
   $ hg help extdiff
   hg extdiff [OPT]... [FILE]...
   
   use external program to diff repository (or selected files)
   
       Show differences between revisions for the specified files, using an
       external program. The default program used is diff, with default options
       "-Npru".
   
       To select a different program, use the -p/--program option. The program
       will be passed the names of two directories to compare, unless the --per-
       file option is specified (see below). To pass additional options to the
       program, use -o/--option. These will be passed before the names of the
       directories or files to compare.
   
       When two revision arguments are given, then changes are shown between
       those revisions. If only one revision is specified then that revision is
       compared to the working directory, and, when no revisions are specified,
       the working directory files are compared to its parent.
   
       The --per-file option runs the external program repeatedly on each file to
       diff, instead of once on two directories. By default, this happens one by
       one, where the next file diff is open in the external program only once
       the previous external program (for the previous file diff) has exited. If
       the external program has a graphical interface, it can open all the file
       diffs at once instead of one by one. See 'hg help -e extdiff' for
       information about how to tell Mercurial that a given program has a
       graphical interface.
   
       The --confirm option will prompt the user before each invocation of the
       external program. It is ignored if --per-file isn't specified.
   
   (use 'hg help -e extdiff' to show help for the extdiff extension)
   
   options ([+] can be repeated):
   
    -p --program CMD         comparison program to run
    -o --option OPT [+]      pass option to comparison program
    -r --rev REV [+]         revision
    -c --change REV          change made by revision
       --per-file            compare each file instead of revision snapshots
       --confirm             prompt user before each external program invocation
       --patch               compare patches for two revisions
    -I --include PATTERN [+] include names matching the given patterns
    -X --exclude PATTERN [+] exclude names matching the given patterns
    -S --subrepos            recurse into subrepositories

   $ hg help --extension extdiff
   extdiff extension - command to allow external programs to compare revisions
   
   The extdiff Mercurial extension allows you to use external programs to compare
   revisions, or revision with working directory. The external diff programs are
   called with a configurable set of options and two non-option arguments: paths
   to directories containing snapshots of files to compare.
   
   If there is more than one file being compared and the "child" revision is the
   working directory, any modifications made in the external diff program will be
   copied back to the working directory from the temporary directory.
   
   The extdiff extension also allows you to configure new diff commands, so you
   do not need to type 'hg extdiff -p kdiff3' always.
   
     [extdiff]
     # add new command that runs GNU diff(1) in 'context diff' mode
     cdiff = gdiff -Nprc5
     ## or the old way:
     #cmd.cdiff = gdiff
     #opts.cdiff = -Nprc5
   
     # add new command called meld, runs meld (no need to name twice).  If
     # the meld executable is not available, the meld tool in [merge-tools]
     # will be used, if available
     meld =
   
     # add new command called vimdiff, runs gvimdiff with DirDiff plugin
     # (see http://www.vim.org/scripts/script.php?script_id=102) Non
     # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
     # your .vimrc
     vimdiff = gvim -f "+next" \
               "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
   
   Tool arguments can include variables that are expanded at runtime:
   
     $parent1, $plabel1 - filename, descriptive label of first parent
     $child,   $clabel  - filename, descriptive label of child revision
     $parent2, $plabel2 - filename, descriptive label of second parent
     $root              - repository root
     $parent is an alias for $parent1.
   
   The extdiff extension will look in your [diff-tools] and [merge-tools]
   sections for diff tool arguments, when none are specified in [extdiff].
   
     [extdiff]
     kdiff3 =
   
     [diff-tools]
     kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
   
   If a program has a graphical interface, it might be interesting to tell
   Mercurial about it. It will prevent the program from being mistakenly used in
   a terminal-only environment (such as an SSH terminal session), and will make
   'hg extdiff --per-file' open multiple file diffs at once instead of one by one
   (if you still want to open file diffs one by one, you can use the --confirm
   option).
   
   Declaring that a tool has a graphical interface can be done with the "gui"
   flag next to where "diffargs" are specified:
   
     [diff-tools]
     kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
     kdiff3.gui = true
   
   You can use -I/-X and list of file or directory names like normal 'hg diff'
   command. The extdiff extension makes snapshots of only needed files, so
   running the external diff program will actually be pretty fast (at least
   faster than having to compare the entire tree).
   
   list of commands:
   
    extdiff       use external program to diff repository (or selected files)
   
   (use 'hg help -v -e extdiff' to show built-in aliases and global options)

 Disabled extension commands:
 
   $ ORGHGRCPATH=$HGRCPATH
   $ HGRCPATH=
   $ export HGRCPATH
   $ hg help email
   'email' is provided by the following extension:
   
       patchbomb     command to send changesets as (a series of) patch emails
   
   (use 'hg help extensions' for information on enabling extensions)
 
 
   $ hg qdel
   hg: unknown command 'qdel'
   'qdelete' is provided by the following extension:
   
       mq            manage a stack of patches
   
   (use 'hg help extensions' for information on enabling extensions)
   [255]
 
 
   $ hg churn
   hg: unknown command 'churn'
   'churn' is provided by the following extension:
   
       churn         command to display statistics about repository history
   
   (use 'hg help extensions' for information on enabling extensions)
   [255]
 
 
 
 Disabled extensions:
 
   $ hg help churn
   churn extension - command to display statistics about repository history
   
   (use 'hg help extensions' for information on enabling extensions)
 
   $ hg help patchbomb
   patchbomb extension - command to send changesets as (a series of) patch emails
   
   The series is started off with a "[PATCH 0 of N]" introduction, which
   describes the series as a whole.
   
   Each patch email has a Subject line of "[PATCH M of N] ...", using the first
   line of the changeset description as the subject text. The message contains
   two or three body parts:
   
   - The changeset description.
   - [Optional] The result of running diffstat on the patch.
   - The patch itself, as generated by 'hg export'.
   
   Each message refers to the first in the series using the In-Reply-To and
   References headers, so they will show up as a sequence in threaded mail and
   news readers, and in mail archives.
   
   To configure other defaults, add a section like this to your configuration
   file:
   
     [email]
     from = My Name <my@email>
     to = recipient1, recipient2, ...
     cc = cc1, cc2, ...
     bcc = bcc1, bcc2, ...
     reply-to = address1, address2, ...
   
   Use "[patchbomb]" as configuration section name if you need to override global
   "[email]" address settings.
   
   Then you can use the 'hg email' command to mail a series of changesets as a
   patchbomb.
   
   You can also either configure the method option in the email section to be a
   sendmail compatible mailer or fill out the [smtp] section so that the
   patchbomb extension can automatically send patchbombs directly from the
   commandline. See the [email] and [smtp] sections in hgrc(5) for details.
   
   By default, 'hg email' will prompt for a "To" or "CC" header if you do not
   supply one via configuration or the command line.  You can override this to
   never prompt by configuring an empty value:
   
     [email]
     cc =
   
   You can control the default inclusion of an introduction message with the
   "patchbomb.intro" configuration option. The configuration is always
   overwritten by command line flags like --intro and --desc:
   
     [patchbomb]
     intro=auto   # include introduction message if more than 1 patch (default)
     intro=never  # never include an introduction message
     intro=always # always include an introduction message
   
   You can specify a template for flags to be added in subject prefixes. Flags
   specified by --flag option are exported as "{flags}" keyword:
   
     [patchbomb]
     flagtemplate = "{separate(' ',
                               ifeq(branch, 'default', '', branch|upper),
                               flags)}"
   
   You can set patchbomb to always ask for confirmation by setting
   "patchbomb.confirm" to true.

 Test order of revisions in compound expression
 ----------------------------------------------
 
 The general rule is that only the outermost (= leftmost) predicate can
 enforce its ordering requirement. The other predicates should take the
 ordering defined by it.
 
  'A & B' should follow the order of 'A':
 
   $ log '2:0 & 0::2'
   2
   1
   0
 
  'head()' combines sets in right order:
 
   $ log '2:0 & head()'
   2
   1
   0
 
  'x:y' takes ordering parameter into account:
 
   $ try -p optimized '3:0 & 0:3 & not 2:1'
   * optimized:
   (difference
     (and
       (range
         (symbol '3')
         (symbol '0'))
       (range
         (symbol '0')
         (symbol '3')))
     (range
       (symbol '2')
       (symbol '1')))
   * set:
   <filteredset
     <filteredset
       <spanset- 0:4>,
       <spanset+ 0:4>>,
     <not
       <spanset+ 1:3>>>
   3
   0
 
  'a + b', which is optimized to '_list(a b)', should take the ordering of
  the left expression:
 
   $ try --optimize '2:0 & (0 + 1 + 2)'
   (and
     (range
       (symbol '2')
       (symbol '0'))
