At least one mistake:

To: unlisted-recipients:; (no To-header on input)

(I guess you've Bcc-ed the Git list, please don't do that)

I don't think so. After a commit, I usually expect the index to be
clean, ready to start preparing the next commit (except if I
explicitely asked the opposite), which implies that the index used for
commit (-i|-p) is the same as the usual one.

... or git add --patch.

If I read correctly, this forbids "git commit --interactive --patch",
while "git add --interactive --patch" is allowed, and equivalent to
"--patch" alone.

Other than that, the patch looks good.
