You can use
darcs diff -- -udp
which probably does what you want (I didn't see the -P option in the diff
manpage). The flags are -rN by default.
Alas, there isn't any way to add this to _darcs/prefs/defaults, since it
relies on a getopt trick (the -- above) to keep the -udp from being
processed as darcs flags. So I just added an option to diff so you can use
darcs diff --diff-opts -udp
which means that you can add to _darcs/prefs/defaults a line:
diff diff-opts -udp
which will make this the default. However, diff-opts is only available in
the latest darcs (and won't even be there for another hour or so, since the
new code will have to pass tests, etc), since I just added it.

Yeah, it's easy. There's no context because it doesn't make sense to store
context in darcs patches--it's just a waste of space. I just haven't
bothered to make an output format that is distinct from the darcs patch

Context would definitely be a nice addition. Also, most people don't want
to see the entire contents of each file they add or remove... but since
darcs diff exists (and I personally have obviously become very accustomed
to the darcs patch format), improving the output of whatsnew (which would
also improve the interactive output of record, etc) is relatively low
