single/double quote escapes codebox highlighter

[nilamo]

I know we've talked about it before, but I can't find where it's mentioned specifically.  Lots of highlighter threads, though.

I think the issue is related to multiple different quote characters near each other, like the highlighter loses track of which one is the enclosing quote, or something, and ends up highlighting too much.  I also think it might be specifically related to single quotes.
