matcher: rescind support for @(rcons ...) patterns.

There is no longer any way to write a @(rcons ...)
pattern using the range syntax, so there is no point in
supporting that operator. The silly syntax @@a..@b
which previously worked was actually due to a mistaken
requirement in the parser.

* share/txr/stdlib/match.tl (compile-range-match): Function
moved closer to compile-atom-match, below compile-vec-match.
The argument is now a range object containing patterns, so we
pull it apart with from and to.
(compile-atom-match): Pass range directly to
compile-range-match; no need to construct (rcons ...) syntax.

* tests/011/patmatch.tl: Add range tests from documentation
and a few others.

* txr.1: References to @(rcons ...) pattern scrubbed.
One wrong #R pattern example corrected.
