It shouldn't be that complex.  IMHO, isstring() should have been renamed 
to isstringconst(), and a new isstring() been implemented that computes 
the above || expression.  Then a single go through all the sources, 
replacing those (few?) uses of isstring() that actually have to be 
isstringconst(), would have sufficed to change the global behaviour.

I.e. isstring() should have changed meaning from "token is a string 
literal" to "token starts a string-valued expression".
