Even when only a single file is specified as an argument to diff?
Wow, that's a lot of spurious IO.

I just tested "darcs diff" against the darcs source repository. I
added a single space to WhatsNew.lhs. Running

  darcs diff -u WhatsNew.lhs

takes about three seconds and grinds the hard disk. Is there supposed
to be a more economical command to ask, "What have I done to my
working copy of a particular file?" Well, I do observe that

  darcs whatsnew WhatsNew.lhs

only takes about a quarter second.
