Re: [PATCH] diff-lib: ignore all outsider if --relative asked

Awesome work, and this not only fixes the crash but a bug in --relative that has been going for a while, after all the documentation clearly says that --relative should filter out entries outside the tree and it does unless in this crashing scenario, which as pointed out was also showing the wrong paths for the diff chunks outside of the directory.

My only concern is that it seems this has been broken for a while (couldn't bisect, but AFAIK the first implementation did filter like this one does), so some people might be expecting the broken behaviour.

got my Tested-by or Reviewed-by and gratitude.
