          2. M-->返回到修改之前的内容
       2. 几种使用revert后的情况
          1. If you modify a file, it will restore the file to its unmodified state.
          2. If you hg add or hg copy a file, it will undo the “added” state of the file, but leave the file itself untouched.
          3. If you delete a file without telling Mercurial, it will restore the file to its unmodified contents.
          4. If you use the hg remove command to remove a file, it will undo the “removed” state of the file,
    2. rollback
       1. hg rollback
       2. 只能回滚一次
       3. 当push之后无法回滚

       1. hg backout
       2. hg backout tip
          1. hg log --style compact
       3. hg backout 非tip版本
          1. 会先创建一个新的head
          2. 使用hg backout --merge
          3. hg commit
       4. 撤销合并
          1. hg backout --rev=4 --parent=2
          2. hg backout --rev=4 --parent=3.
          3. 最后merge这2个新的head
