As explained in section 6 Notation, the construct [^abc] matches any 
Char with a value not among the characters given.  This means [^%&"] 
matches any character except %, & and ", which is the desired behaviour 
for double-quote-delimited literals.  Similarly, [^%&'] excludes ' for 
single-quote-delimited literals.
