For diff family commands, we can tell them to exclude changes outside of some directories if --relative is requested. In diff_unmerge(), NULL will be returned if the requested path is outside of the interesting directories, thus we'll run into NULL pointer dereference in run_diff_files when trying to dereference its return value. Checking for return value of diff_unmerge before dereferencing is not sufficient, though. Since, diff engine will try to work on such pathspec later. Let's not run diff on those unintesting entries, instead. As a side effect, by skipping like that, we can save some CPU cycles.
