Is that very hard? filestore has that functionality, after all. IIRC,
it was basically 'darcs changes --from-match="hash foo"
--to-match="hash foo" file'.
Darcs changes gives list of patches. What I need is compare two versions of a file.

darcs diff --to-patch="my previous patch" file.cpp

This gives me the changes, but I'd have to parse the diff format, and process the file out of it. I'd rather have some darcs person to create a command like

darcs diff [any combination of patches for the first version] [any combination of patches for the second version] filename tempfile1 tempfile2

and I could just run kdiff with tempfile1 tempfile2.

darcs diff  is slow too, but that's minor.
