Here's an alternative that might a bit more portable, emacs-centric and
user-friendly: just yank the patch region to a new buffer and `M-x
diff-mode' there. Then you can `C-c C-c` and `C-c C-a` at will,
applying, undoing and reading the differences as you go.

If you're lazy, don't mark and yank to a new buffer, just `M-x
diff-mode` whatever buffer you find the message in.

diff-mode will ask you to locate the file. Alternatively, use `M-x cd`
on that buffer to switch to the root of the project the patch pertains
too. I think I've seen diff-mode automagically guessing the file but I'm
too lazy right now to figure out and describe under which conditions
that happens, if at all.
