   $ hg help cleanstatus
   hg cleanstatus [ONLYHELPHERE]
   
   alias for: hg status -c
   
   show changed files in the working directory
   
       Show status of files in the repository. If names are given, only files
       that match are shown. Files that are clean or ignored or the source of a
       copy/move operation, are not listed unless -c/--clean, -i/--ignored,
       -C/--copies or -A/--all are given. Unless options described with "show
       only ..." are given, the options -mardu are used.
   
       Option -q/--quiet hides untracked (unknown and ignored) files unless
       explicitly requested with -u/--unknown or -i/--ignored.
   
       Note:
          'hg status' may appear to disagree with diff if permissions have
          changed or a merge has occurred. The standard diff format does not
          report permission changes and diff only reports changes relative to one
          merge parent.
   
       If one revision is given, it is used as the base revision. If two
       revisions are given, the differences between them are shown. The --change
       option can also be used as a shortcut to list the changed files of a
       revision from its first parent.
   
       The codes used to show the status of files are:
   
         M = modified
         A = added
         R = removed
         C = clean
         ! = missing (deleted by non-hg command, but still tracked)
         ? = not tracked
         I = ignored
           = origin of the previous file (with --copies)
   
       Returns 0 on success.

 "--" may be an option value:

   abort: repository -- not found
   [255]
   $ hg log -T --
   -- (no-eol)
   $ hg log -T -- -k nomatch
 
 Parsing of early options should stop at "--":
 
   $ hg cat -- --config=hooks.pre-cat=false
   --config=hooks.pre-cat=false: no such file in rev cb9a9f314b8b
   [1]
   $ hg cat -- --debugger

 Unparsable form of early options:
 
   $ hg cat --debugg
   abort: option --debugger may not be abbreviated
   [255]
 
 Parsing failure of early options should be detected before executing the
 command:
 
   $ hg log -b '--config=hooks.pre-log=false' default
   abort: option --config may not be abbreviated
   [255]
   $ hg log -b -R. default
   abort: option -R has to be separated from other options (e.g. not -qR) and --repository may only be abbreviated as --repo
   [255]
   $ hg log --cwd .. -b --cwd=. default
   abort: option --cwd may not be abbreviated
   [255]
 
 However, we can't prevent it from loading extensions and configs:
 
   $ cat <<EOF > bad.py
   > raise Exception('bad')
   > EOF
   $ hg log -b '--config=extensions.bad=bad.py' default
   *** failed to import extension bad from bad.py: bad

   $ hg log -b '--config=profiling.enabled=yes' 2>&1 | grep -i sample
   Sample count: .*|No samples recorded\. (re)
 
 Early options can't be specified in [aliases] and [defaults] because they are
 applied before the command name is resolved:
 
   $ hg log -b '--config=alias.log=log --config=hooks.pre-log=false'
   hg log: option -b not recognized
   error in definition for alias 'log': --config may only be given on the command
   line
   [255]
 
   $ hg log -b '--config=defaults.log=--config=hooks.pre-log=false'
   abort: option --config may not be abbreviated
   [255]
 
 Shell aliases bypass any command parsing rules but for the early one:
 
   $ hg log -b '--config=alias.log=!echo howdy'
   howdy
 
 Early options must come first if HGPLAIN=+strictflags is specified:

 Test obsolescence behavior

 successors should be taken in account when checking head destination

 Test that 5 is detected as a valid destination from 3 and also accepts moving
 the bookmark (issue4015)
 
   $ hg up --quiet --hidden 3
   $ hg up 5
   1 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ hg book bm

 Test that we abort before we warn about the hidden commit if the working
 directory is dirty
   $ echo conflict > a
   $ hg up --hidden 3
   abort: uncommitted changes
   (commit or update --clean to discard changes)
   [255]
 
 Test that we still warn also when there are conflicts
   $ hg up -m --hidden 3
   merging a
   warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
   0 files updated, 0 files merged, 0 files removed, 1 files unresolved
   use 'hg resolve' to retry unresolved file merges
   (leaving bookmark bm)

 Test that we don't crash when updating from a pruned changeset (i.e. has no
 successors). Behavior should probably be that we update to the first
 non-obsolete parent but that will be decided later.
