Neat.

I would tweak it a little.  People might be using typedefs
for character strings that wrap, say, "unsigned char".
So if you're going to do a heuristic on the name, treat
it as a character string if the name ends in "char" (not 
necessarily with a preceding space) or "char_t" (because
many people use _t as the suffix for typedef names).
