将Emacs指针移动到Perforce提交消息的特定文本的开头

Question

如何将Elisp中的点移动到<enter description here>的开头并删除该文本。我想把它放在我的〜/ .emacs-p4中，这是通过P4EDITOR使用的，

$ echo $P4EDITOR
emacs -nw --no-init-file --no-splash --load ~/.emacs-p4

p4 submit的模板用途是：

# A Perforce Change Specification.
#
#  Change:      The change number. 'new' on a new changelist.
#  Date:        The date this specification was last modified.
#  Client:      The client on which the changelist was created.  Read-only.
#  User:        The user who created the changelist.
#  Status:      Either 'pending' or 'submitted'. Read-only.
#  Description: Comments about the changelist.  Required.
#  Jobs:        What opened jobs are to be closed by this changelist.
#               You may delete jobs from this list.  (New changelists only.)
#  Files:       What opened files from the default changelist are to be added
#               to this changelist.  You may delete files from this list.
#               (New changelists only.)

Answer 1

我认为（没有测试）您需要做的就是：

(search-forward "<enter description here>")
(delete-region (line-beginning-position) (line-end-position))
