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.

   i found git notes can note things, but it add in patch not
   cover letter. is some operate can do to save in cover letter.

   and the git note record with commit, when amend it can lost note,
   is the rewrite error?

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.

Have you set the config `notes.rewriteRef` to your notes ref?

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.
