No quote fontification.

Why?  If documents don't use guillemets and the fontification gets
garbled, why not have a way to turn it off?  Why is the variable
called font-latex-quotes if it really only works on guillemets?

Then its name might be not the best choice.  Both name and doc string
imply that it is suppsed to work on any quotes.

They do.

This is like \chapter*: the real macro is called \<, but if it is
called with a suffix of < following it, the \WithSuffix definition
gets used.

suffix.sty is a fun little style file...
