Hm, this "works", but it definitely isn't nice, and doesn't work when
you type the shorter path manually first.
# Untracked files:
#	Src/Modules/curses_keys.h
if i'm sitting in Src/Builtins, the following code will produce
git add <tab>
git add ../<tab>
git add ../../<tab>
git add ../../Src/Modules<tab>
git add ../../Src/Modules/curses_keys.h
which is not so great.
Annoyingly, when i'm sitting in Src/Builtins, git status produces the following
# Untracked files:
#	../Modules/curses_keys.h

I don't know how often one really wants to git add files above the
current dir, but it just annoys me that it's so hard to fix. :)
