I like the idea of handling line directives, whichever way we go with
the other cpp-related proposals. The fact that these are
distinguished from a propnodename beginning with # only by the
following digits is more subtle than I'd ideally like, but I think
it's wirth it.
The only thing I would like to see change is to only recognize line
directives at the beginning of the line (in fact, preferably in column
0 only). Unfortunately that is going to mean some mucky flex work,
including a new start state, I expect.
