Clean up b4_check_percent_code_qualifiers a little.

Browse Source 
* data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
in b4_used_percent_code_qualifiers to be double-M4-quoted.  Rewrite
documentation and add examples.
* src/parse-gram.y (grammar_declaration): Double-M4-quote those
qualifiers here.
