parser: fix bad precedence of @ token.
Whereas @a..@b parses and transforms to (rcons @a @a),
@(a)..@(a) goes to @(rcons a @(a)).
* parser.l (grammar): Under 248 compatibility or lower, the @
character now produces the OLD_AT token. Otherwise it produces
the '@' character, as before.
* parser.y (OLD_AT): New token replaces the '@' at the old
low precedence position. '@' is now at the highest precedence,
together with OLD_DOTDOT. (We don't care about interactions
between '@' and OLD_DOTDOT, because OLD_DOTDOT only exists in
185 compatibility, in which '@' is OLD_AT).
(meta): The two rules have to be unfortunately duplicated for
OLD_AT, since there is no BNF OR operator in Yacc.
* txr.1: Compat note added.
* lex.yy.c.shipped: Updated.
* y.tab.c.shipped, y.tab.h.shipped: Likewise.
