rHGdb69a763bc89: diff: make --stat respect ui.relative-paths

Summary

It would have been easy to make all diffs respect ui.relative-paths,
but we don't want that since it makes the diff invalid. Perhaps it
makes sense to do that with --noprefix since the point of that is to
make paths that are easy to copy&paste, and the diff is already
invalid anyway. But this patch just makes the --stat version respect
the config option. The --stat view is not even close to a valid diff,
so I think it makes sense to show the paths in more human-friendly
form.

Seems fine, but I'm not sure about the Windows behavior:

Do we want to see backslash paths on Windows?
Backslash paths are parsed correctly?

I would assume that we want that.

Backslash paths are parsed correctly?

Good question! Some simple testing I just did suggests that it does work.
