Re: [PATCH v2 14/14] Add git-check-ignore sub-command

This breaks when your shell is not "bash".

+test_check_ignore () {
+	args="$1" expect_code="${2:-0}" global_args="$3"
+
+	init_vars &&
+	rm -f "$HOME/stdout" "$HOME/stderr" "$HOME/cmd" &&

+		>"$HOME/cmd" &&

Don't use which in scripts.  Is this just leftover cruft from debugging?
