Introducing word list literals.
* parser.l (WLIT): New exclusive start state.
Extend lexical grammar to transition to WLIT state upon
the #" or #*" sequence which kicks off a word literal,
and in that state, piecewise lexically analyze the literal,
mostly by borrowing rules from other literals.
* parser.y (WORDS, WSPLICE): New tokens.
(n_exprs): Integrate splicing form of word list literal syntax.
(n_expr): Integrate non-splicit for of word list literal syntax.
(litchars): Propagate line number info.
(wordslit): New grammar rule.
* txr.1: Updated.
