Hmmm, supporting -E is trivial at present, even when integrated.  I'm
starting to believe a temporary file file for -traditional is the
right way to go.

I still have a problem to fix with &&, though, since the new lexer
sees

#if 1 &/**/& 1

as containing a single && token.  It should be easily fixable through
a new TRAD_COMMENT flag for the initial & token, or suchlike, which
would be treated as a whitespace separator without actually outputting
whitespace.
