Hi:
   i have question about format-patch.

   when use git format-patch with --cover-letter, we add information
   in the cover letter. and then, i must send patch with -v2, the
   information in the cover letter is lost in the v2 patch.

...
You can try using `git branch --edit-description <branch_name>` and
write the contents of the cover letter there. Then you can use the
option `--cover-from-description` to use the branch description when
generating the cover letter.

Another thing people are encouraged to do is to use the -o option to
store iterations of your series on disk, perhaps in the same
directory.  When you edit v2-0000-cover-letter.txt file, you can
then reference the previous one you've already sent easily that way.
