matcher: new @(coll) operator.
* share/txr/stdlib/match.tl (compile-loop-match): Implement
coll semantics. coll fails if it collects nothing, which
uses common logic with all*. We just have to move the
flipping of the loop-iterated-var into the match, and not
do it unconditionally for every iteration.
(compile-match): Hook in the coll operator.
* tests/011/patmatch.tl: Test case copied from doc example.
* txr.1: Documented.
