Help for uncommit

  $ hg help uncommit

  hg uncommit [OPTION]... [FILE]...

  uncommit part or all of a local changeset

      This command undoes the effect of a local commit, returning the affected

      files to their uncommitted state. This means that files modified or

      deleted in the changeset will be left unchanged, and so will remain

      modified in the working directory.

      If no files are specified, the commit will be pruned, unless --keep is

      given.

  (use 'hg help -e uncommit' to show help for the uncommit extension)

  options ([+] can be repeated):

      --keep                     allow an empty commit after uncommiting

      --allow-dirty-working-copy allow uncommit with outstanding changes

   -I --include PATTERN [+]      include names matching the given patterns

   -X --exclude PATTERN [+]      exclude names matching the given patterns

   -m --message TEXT             use text as commit message

   -l --logfile FILE             read commit message from file

   -d --date DATE                record the specified date as commit date

   -u --user USER                record the specified user as committer

  (some details hidden, use --verbose to show complete help)

Uncommit with no commits should fail

  $ hg uncommit

  abort: cannot uncommit null changeset

  (no changeset checked out)
