Mercurial修改历史changeset

（源信息来自stackoverflow...）

‍ - Enable the MQ extension, by adding something like this to your hgrc:

      [extensions]
      mq =

- 修改最后一次ci的注释：

    - Import the current changeset into the queue:

      hg qimport -r .

    - Refresh the patch, and edit the commit message:

      hg qrefresh -e

    - Finish all applied patches (one, in this case) and store them as regular changesets:

      hg qfinish -a

- Imagine, you have 5 commits, and your erroneous commit message is in r.3.

  hg qimport -r 3:tip
  hg qpop -a
  vi .hg/patches/3.diff
  (change the comment, after the mercurial header)
  hg qpush -a
  hg qdelete -r qbase:qtip
