[PATCH 5/8] test-lib.sh: Add a test_set_editor function to safely set $VISUAL

From: Bryan Donlan <bdonlan@fushizen.net>
Date: Apr 9, 2008, 01:30 UTC
Message-ID: <1207704604-30393-5-git-send-email-bdonlan@fushizen.net>
In-Reply-To: <1207704604-30393-4-git-send-email-bdonlan@fushizen.net>

In particular, this function correctly handles cases where the pwd contains spaces, quotes, and other troublesome metacharacters.
