Dears Hamano,

Sorry about the late submission, and I have modified it to support the `--empty-commit=(die|skip|asis)` pattern.

Show 13 quoted lines

When it comes to the last test case, there are some accidental contents recognized as commit messages inside an empty patch, like:

1. version signatures:
  > -- 
  > 2.34.0.rc2.390.gef33ce8c6f
2. information of cover letter:
  > *** BLURB HERE ***
  >
  > A U Thor (1):
  >   empty commit

I don't think it is necessary to fix it within `mailinfo.c`. Can you give me some suggestions on whether this case should be handled?
