Ah-ah, that's a useful new capability, which trumps an undocumented
syntax tolerance (which should only ever have been invoked accidentally
anyway), I think. Even if any half-decent pre-processor ought to be able
to concatenate component substrings when it is building a single
NUL-terminated one, this would simplify and speed up the task.
