You might try generating your cover letter template via git format-patch
--cover-letter, which will automatically give you a list of patches and
a git-produced diffstat; much easier than trying to format a cover
letter by hand. Meanwhile, you might consider sending your patches as a
bug report to diffstat upstream: Thomas E. Dickey
<dickey@invisible-island.net>.
