format-patch: use branch description in cover letter

Use the description for the branch when preparing the cover letter
when available.

While at it, mark a loosely written codepath that would do a random and
useless thing given an unusual input (e.g. "^master HEAD HEAD^"), which
we may want to fix someday.
