I can't get the above snippet to work, but maybe I'm doing something wrong.
I had a problem with the newline between the key and the value. bash
gives me the whole line in the loop, but when I try to trim it $i is
treated as two values. I couldn't figure out any other way to do it,
besides piping $i to cut or tr.
Maybe a better solution would be to add --keys-only or something to
git-config?
