Revision to .. syntax.
* parser.y (r_exprs, n_expr): Move the DOTDOT syntactic sugar rule from
r_exprs to n_expr, where it is much simpler. This also means that the
a..b syntax is now an expression by itself; it need not be enclosed in
a list. The DOTDOT operator is made right associative; or rather
its existing %right declaration is now activated.
* txr.1: Remove documentation stating that the .. notation must
be used in a list, and not in the dotted position of an improper
list. Document the behavior in the dotted position, and document
right associativity.
