In the lexer check if a number ends in digit separator.  If so back up.

This is testing...
The new test case is the one here in the trail.

--- Comment #1 from Ben Longbons  ---
Demostration that gcc correctly preprocesses the other tokens:

#define JOIN(a, b) a##b
JOIN(.., .)
// error about pasting . and .

#define JOIN3(a, b, c) a##b##c
JOIN3(%:%, :, %:)
// successfully results in %: %:%:
// (though note that the order of evaluation of ## is unspecified so if b##c
were evaluated first a compliant implementation could fail to paste :%:)
