rule-syntax-check: values can contain escaped double quotes

This is true since commit 7e760b79ad143b26a5c937afa7666a7c40508f85.

Note that the changes in the regex expressions relies on the fact that the
script assumes that the comma separator is mandatory.

Add a comment in the script to clarify this.
