Allow directives after variable to be a kind of negative match.

* match.c (search_form): bugfix: return correct match extent.

* parser.y: Adjusting associativity and precedence of directives, IDENT,
and grouping tokens once again. This is so that a var followed by
a directive will turn into one elem, rather than the var being
reduced to an elem first.

* txr.1: Revised documentation to mroe clearly define the concept
of a negative match, broken into subsections. Some sections
belonging to syntax were moved to an appropriate location.
Subsections added to description of form syntax.
Explanation of directive-driven syntax.
