  hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...

  update the current patch

      If any file patterns are provided, the refreshed patch will contain only

      the modifications that match those patterns; the remaining modifications

      will remain in the working directory.

      If -s/--short is specified, files currently included in the patch will be

      refreshed just like matched files and remain in the patch.

      If -e/--edit is specified, Mercurial will start your configured editor for

      you to enter a message. In case qrefresh fails, you will find a backup of

      your message in ".hg/last-message.txt".

      hg add/remove/copy/rename work as usual, though you might want to use git-

      style patches (-g/--git or [diff] git=1) to track copies and renames. See

      the diffs help topic for more information on the git diff format.

      Returns 0 on success.
