Does Emacs have a patch parser? I mean, something that would take a
region of text and return all the pertinent parts of the patch it finds
there?
I've been digging through `diff-mode', and it's very geared towards
interactive use. But I may well be missing something there.
My use case here is that I want to find out where to apply a patch
automatically for my new Super Maintainer Mode thing.

should obviously be run from <top>/lisp with -p1 (or in <top> with -p0),
while this is in <top> with -p1:
--- a/lisp/net/eww.el
+++ b/lisp/net/eww.el
It's not rocket surgery to write this myself, but if it already exists...

I think the closest we have is the code in diff-mode.

FWIW, I currently use M-| M-p which (almost) always brings me to
a command like "cd ~/.../emacs/emacs-24; patch -p1", and it's really not
much work for me to adjust the -p1 to -p0 at the same time as I check
whether I want to change the "emacs-24" into a "master".
