I'm not very confident in the whole thing, but if you think it works,
that's fine.

It looks like the tokens in question always include some sort of
terminator; the natural terminator when the token points to the
source, a space for artificial numeric macros (with this patch), and
null for tokens created through token pasting (which looks kind of
suspicious...).  Is there some sort of guarantee about the token
including some sort of separator after the token?
