wordchrs - set up word-chr list for word-boundary stuff, if needed
The list is kept as a bunch of arcs between two dummy states; it's
disposed of by the unreachable-states sweep in NFA optimization.
Does NEXT().  Must not be called from any unusual lexical context.
This should be reconciled with the \w etc. handling in lex.c, and
should be cleaned up to reduce dependencies on input scanning.
