[PATCH] Be careful with symlinks when detecting renames and copies.

Earlier round was not treating symbolic links carefully enough,
and would have produced diff output that renamed/copied then
edited the contents of a symbolic link, which made no practical
sense.  Change it to detect only pure renames.
