In general, I am not all that interested in adding anything new to
contrib/ as git.git has matured enough, but even if this will stay
outside my tree, there are a few interesting things to note to help
its eventual users.

Is address being used elsewhere, or is this a remnant from an
earlier debugging or something?

This may need to be tightened if you want to use this on a
real-world project (git.git itself does not count ;-); you may see
something like:
diff --git "a/a\"b" "b/a\"b"
(I did an insane pathname 'a"b' to get the above example, but a more
realistic is a character outside ASCII).

This may want to be a bit more careful for a hunk that adds to an
empty file, which will give you something like
@@ -0,0 +1 @@
@@ -0,0 +1,200 @@
Nobody sane would use -U0 when doing a format-patch, but if this
wants to accomodate such a patch as well, it needs to ignore a hunk
that only adds new lines.
