AFAIK, there is not a way to do it in the general case (though there are
specific config options for things like rename support). When I
refactored the gitattributes diff=$foo code a few months back, I tried
to keep in mind the possibility of a "diff options" field. But I never
actually implemented anything, as I don't personally ever use diff
options in such a way.

If you're interested, it would probably not be too hard to implement
(see userdiff.[ch], and the external and textconv code in diff.c for a
start).
