I didn't mention it but this hits the same snag as "[\"']", the real

which gets messy with \\\$ etc malarky without the single quotes.
Hmmm, actually, this is wrong. I was getting confused with matching a trailing $ which is the case where "\\\$" and '\$' matters.
Maybe switching to " will be best.
