PATCH: more _arguments tests

[Oliver Kiddle <okiddle@yahoo.co.uk>]

This adds tests covering the two fixes I've made recently plus Daniel's
fix for opt_args quoting. There's also tests covering exclusion lists
and -A/-S options. When applying exclusion lists, _arguments should
ideally look forward on the line with the opposite logic applying.
So with '(-b)-a' '-b', -a would not be completed if -b appears later on
the line.

Does anyone know how to get gcov working with source files from zsh
modules? It doesn't seem to like computil.c having been compiled to
computil..o.
