So you create non/git/sub, go to non/git (so there is sub/ directory), and try running "..".
If you had a directory non/tig next to non/git and used ../tig instead of .. as the path given to "git grep", it would also correctly fail. Searching in a non-existing path, ../non, dies in a different error, with an error message that is not technically wrong, but it probably can be improved. It has been a while since I looked at the pathspec matching code, but if we are lucky, it might be just the matter of swapping the order of checking (in other words, check "is it outside" first and then "does it exist" next, or something like that)?
