diff.c: do not use pathname comparison to tell renames
The final output from diff used to compare pathnames between preimage and postimage to tell if the filepair is a rename/copy. By explicitly marking the filepair created by diffcore_rename(), the output routine, resolve_rename_copy(), does not have to do so anymore. This helps feeding a filepair that has different pathnames in one and two elements to the diff machinery (most notably, comparing two blobs). Signed-off-by: Junio C Hamano <junkio@cox.net>
