Shorthand for filters which map multiple texts to a common

replacement text.

* filter.c (build_filter_from_list): Allow tuples to denote
multiple keys mapping to the same value.

* lib.c (do_curry_123_2, do_curry_123_1): New static functions.
(curry_123_2, curry_123_1): New functions.

* lib.h (curry_123_2, curry_123_1): New functions declared.

* match.c (v_deffilter): Allow tuples of strings rather than
just pairs.

* txr.1: Updated.
