This looks somewhat ugly for two reasons.
* The abstraction add_exclude() offers to its callers is just to
let them add one pattern to the list of patterns for the kind
(here, EXC_CMDL); why should they care about .ary[0] part? Are
there cases any sane caller (not the implementation of the
exclude_list_group machinery e.g. add_excludes_from_... function)
may want to call it with .ary[1]? I do not think of any.
Shouldn't the public API function add_exclude() take a pointer to
the list group itself?
* When naming an array of things, we tend to prefer naming it
type thing[count]
so that the second element can be called "thing[2]" and not
"things[2]". dir.exclude_list_group[EXC_CMDL] reads beter.

This is another example where the caller would wish to be able to say
add_exclude(arg, "", 0, group);
instead.
