This is a first very preliminar patch, mostly so people can comment
early on the big picture. It has a number of limitations, many but
not all already listed as FIXME's in the patch itself. If anything in
this patch seems so wrong it is not worth polishing it, it's the
perfect time to say so :)
The idea is to add a new pass to diffcore-rename, to group file renames
looking like a full directory move, and then to hide those file
renames which do not carry any additionnal information.
Here is a sample run:
$ ./git-diff-tree ee491 --factorize-renames -r
[DBG] possible rename from arm/ to bar/
[DBG] possible rename from ppc/ to moved/
[DBG] discarding dir rename of arm/, mixing moved/ and bar/
[DBG] ppc/* -> moved/* makes ppc/sha1ppc.S -> moved/sha1ppc.S uninteresting
[DBG] ppc/* -> moved/* makes ppc/sha1.c -> moved/sha1.c uninteresting
