Bi-directional string tree match for non-vars.
There is an inconsistency in @(bind) in that
given @(bind x y) where x is a variable, both
directions are tried for a string tree match.
x could be tree of strings and y a string atom,
or vice versa. But if x is just an atom, or
a Lisp evaluation, then only one direction is
tried. @(bind @(list "a" "b") "a") succeeds,
but @(bind "a" @(list "a" "b")) fails.
* match.c (dest_bind): Test both directions
in the scalar and Lisp evaluated cases of the
left hand side. Subject to compatibility,
just in case.
* txr.1: Compat note added.
