Sorry, I missed this earlier. I didn't look too closely at the patch
because I think I'm missing a couple things.

1. What is the problem you're trying to address? I understand it had to do
with weird quoting, but I can't tell what the issue is.

2. What exactly is the patch intended to do? It's light on commit messages
and comments.
