>From the quick look it appears that src/pch.c::intuit_diff_type() is the
place where it could be done, with inname and outfile set according to
rename from/rename to lines.  Might need some flag to make the damn thing
reset outfile when we are done with this one; hopefully, the next call
of intuit_diff_type() wouldn't be too late for that, but that's just from
a very cursory reading of the code.

Andreas, do you have anything of that kind queued?  If not, I'll probably
take a stab at that (handling git -M output, that is).
