Filtering on lists and nested lists is hereby made to work.

For instance given @(bind a ("a" "b" "c")) it is now possible
to do @(filter :upcase a) whereby a promptly takes on the value
("A" "B" "C").

* filter.c (string_filter): Function renamed to string_tree_filter.
(compound_filter): Follows rename.
(filter_string): Function renamed to filter string tree.
Can filter tree of strings, or possibly other objects,
if the filter function allows.
(filter_equal): No special case test for objects that are strings.
Just put them through the filter.

* filter.h (filter_string): Declaration updated.

* match.c (format_field, subst_vars, v_filter): Follow rename.

 	* match.c (v_output): Bugfix: we should flush the stream
 	after each @(output) block. Otherwise if output blocks
 	that go to standard output are interleaved with output blocks
