I think diff -u is better when the goal is to show just the
differences, but diff -c is better for changes in the middle of
non-trivial code.

Maybe it will help to send patches as inline text/x-patch attachments?
Such attachments are highlighted by diff-mode in the article buffer
(at least in Gnus), so after customizing diff mode faces it would be
easier to see which lines are old or new.

OK, I will remember to send patches with diff -c.

Since `default-frame-background-mode' is not a user option, but an
internal variable, then maybe it should be mentioned under the `Lisp
Changes in Emacs 22.1' section of etc/NEWS?
