This makes "git format-patch" a built-in.
* js/fmt-patch:
git-rebase: use canonical A..B syntax to format-patch
git-format-patch: now built-in.
fmt-patch: Support --attach
fmt-patch: understand old <his> notation
Teach fmt-patch about --keep-subject
Teach fmt-patch about --numbered
fmt-patch: implement -o <dir>
fmt-patch: output file names to stdout
Teach fmt-patch to write individual files.
Use RFC2822 dates from "git fmt-patch".
git-fmt-patch: thinkofix to show [PATCH] properly.
rename internal format-patch wip
Minor tweak on subject line in --pretty=email
Tentative built-in format-patch.
