I think you meant "remove the escaping" or simply "unescape", not
"remove them", which I'd understand as "remove the quotes".

Other than that, the patch looks good to me, including your proposed
fixup:

I wouldn't worry too much about corner-cases, but perhaps some people do
use escaped quotes inside escaped quotes. I'd say they get what they
deserve ;-).
