With "git add -e [<files>]", Git will fire up an editor with the current
diff relative to the index (i.e. what you would get with "git diff
[<files>]").
Now you can edit the patch as much as you like, including adding/removing
lines, editing the text, whatever. Make sure, though, that the first
character of the hunk lines is still a space, a plus or a minus.
After you closed the editor, Git will adjust the line counts of the hunks
if necessary, thanks to the --recount option of apply, and commit the
patch. Except if you deleted everything, in which case nothing happens
(for obvious reasons).

I actually promised myself not to resend this patch, but a
certain guy who has a hat now asked for it.
