I'm just toying with a hack for simulating 'darcs cat'...

darcs diff --diff-command "cat %2" --to-patch $PATCH $FILE

with a bit of hacking i might be able to get this to work. In fact
this'll solve the encodings/xml problem as well!

Unfortunately I can't do this on windows because %2 expands to a
filename with forward slashes and the 'type' command (equivalent of cat)
understands only backslashes! :( Perhaps i can fallback to using
annotate on windows.
