That only helps for the simplest wildcard, "*".  For anything more complex, say
"foo*", you'll end up with tok_identifier("foo") followed by tok_operator("*"),
whereas outside of the preprocessor it's a single tok_identifier("foo*").

I thought about peeking ahead to the next token and merging them, but you also
need to make sure that we don't merge them when they truly are two tokens, like
"foo *" (which in a probe point should be a syntax error).

Anyway if we figure this out, I suggest making that kludge permanent, and remove
the equally kludgy wildcard flag from the tokenizer.
