I don't understand why the name says either "tight" or "balanced".  As far 
as I can see, c_parser_check_tight_balanced_raw_token_sequence isn't 
checking for balanced token sequences (in the sense defined in C2x) at all 
and would accept e.g. }]{[ as being balanced.  Is that really what's 
supposed to be accepted there?  If it is, the comment on the function 
definition needs to explain the exact definition of what token sequences 
are accepted.
