make all commands be repo-wide by default

- refactor code in commands.py so that:
  if no pattern is given, the command will be repo-wide
  else it will work on the working dir
- update the doc
- fix the tests

     '''Iterate over files and the revs they changed in.
 
     Callers most commonly need to iterate backwards over the history
     it is interested in.  Doing so has awful (quadratic-looking)
     performance, so we use iterators in a "windowed" way.
 
     We walk a window of revisions in the desired order.  Within the
     window, we first walk forwards to gather data, then in the desired
     order (usually backwards) to display it.
 
     This function returns an (iterator, getchange) pair.  The
     getchange function returns the changelog entry for a numeric
     revision.  The iterator yields 3-tuples.  They will be of one of
     the following forms:
 
     "window", incrementing, lastrev: stepping through a window,
     positive if walking forwards through revs, last rev in the
     sequence iterated over - use to reset state for the current window
 
     "add", rev, fns: out-of-order traversal of the given file names
     fns, which changed during revision rev - use to gather data for
     possible display
 
     "iter", rev, None: in-order traversal of the revs earlier iterated
     over with "add" - use to display data'''

     The files will be added to the repository at the next commit.

 hg add [OPTION]... [FILE]...
 
 add the specified files on the next commit
 
     Schedule files to be version controlled and added to the repository.
 
     The files will be added to the repository at the next commit.
 
-    If no names are given, add all files in the current directory and

+    If no names are given, add all files in the repository.
 
 options:
 
  -I --include  include names matching the given patterns
  -X --exclude  exclude names matching the given patterns
 hg diff [-a] [-I] [-X] [-r REV1 [-r REV2]] [FILE]...
 
-diff working directory (or selected files)
+diff repository (or selected files)
 
     Show differences between revisions for the specified files.
 
     Differences between files are shown using the unified diff format.
 
     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.
 
     Without the -a option, diff will avoid generating diffs of files
     it detects as binary. With -a, diff will generate a diff anyway,
     probably with undesirable results.
 
 options:
 
  -r --rev      revision
  -a --text     treat all files as text
  -I --include  include names matching the given patterns
  -X --exclude  exclude names matching the given patterns
 hg status [OPTION]... [FILE]...
 
 show changed files in the working directory
 
-    Show changed files in the working directory.  If no names are
-    given, all files are shown.  Otherwise, only files matching the
-    given names are shown.
+    Show changed files in the repository.  If names are
+    given, only files that match are shown.
 
     The codes used to show the status of files are:
     M = modified
     A = added
     R = removed
     ? = not tracked
 
 aliases: st
 
 options:
 
  -m --modified   show only modified files
  -a --added      show only added files
  -r --removed    show only removed files
  -u --unknown    show only unknown (not tracked) files
  -n --no-status  hide status prefix
  -0 --print0     end filenames with NUL, for use with xargs
  -I --include    include names matching the given patterns
  -X --exclude    exclude names matching the given patterns
 hg status [OPTION]... [FILE]...
 
 show changed files in the working directory
