   Good idea, then with a prefix argument e.g. 'C-u C-c C-A' could save
   the buffers after applying the entire patch.

That doesn't rhyme with the behaviour of C-c C-a which is to reverse
the hunk.  It would make more sense to provide a "Save all files
touched by diff-mode" key, that lists the files, and you can answer
yes or now.  This could then also be used when applying hunks in a
singular fashion.

   It's possible to detect hunk boundaries that start/end inside the
   selected region.

Too much DWIM for my taste ... and might have weird behaviour.
