PQ+ parsing queries with " inside a regex

[ElenaIrimia]

The Regex is matched until it finds ", than a new segment is matched for the rest of the string.
E.G:
query: ""-key" is parsed like:

(request (query (sequence (segment (token (key (regex "")))) (segment (token (key -key))))) <EOF>);

We would want such a query to not be parsed at all. The behaviour for the verbatim similar query ''-key' that I didn't manage to reproduce for regex is that it returns:

(request (query ' ' -key ') <EOF>)

We would want the same for ".
The same for CQP, I couldn't find a solution to rewrite the grammar properly. There both ""-key" and ''-key' are wrongly parsed.

I would expect this to fail.
