matcher: allow pat/var argument: @[expr var pat]
* share/txr/stdlib/match.tl (compile-dwim-predicate-match):
Drop redundant bindable check of sym, since compile-var-match
checks this. Support third argument which gives a pattern or
variable which captures the value from the predicate function,
which might be interesting (not just true/false).
* tests/011/patmatch.tl: New tests.
* txr.1: Documented.
