My gcc refuses to cooperate, giving me SEGV at line 666 or combine-diff, so
I'll ask instead of testing.
Do absolute paths to diff still work without exiting?
They should, as long as they name inside work tree paths.
As far as I know, the bolted-on "work on files outside" code does not feed
the paths to get_pathspec() (and it shouldn't --- that mode is not a git
operation to begin with, and should work even without having a work tree,
so there is no valid base to make the paths relative to).
But it needs to be checked.
