Well Tim suggests using lsdiff in concert with sed to generated file-by-file patches.
Yep, got them installed, but ...
Robert said "Use difftools to separate out the unified patches into one
patch per file."
And I'm particularly interested in this because I'm currently using a fairly
pathetic homegrown perl script to do this. (patchutils won't).
Andrew Morton has some slick scripts to manage patchsets, perhaps one of them might give you the necessary inspiration?

Sorry I don't have any other suggestions...
Cheers,
