Funny, I recently looked at "git format-patch --help" and read that "-D"
is explicitly described as "The resulting patch is not meant to be applied
with patch or git apply; this is solely for people who want to just
concentrate on reviewing the text after the change."

So, no, I think it is anti-social to send such a patch generated with -D
unless it is purely for discussion. The side that generates the patch
should be told to drop "-D" when running the format-patch command,
or perhaps format-patch should be taught to error out when "-D" is
given, perhaps?
