An alternative is to use OPT_STRING_LIST and then convert in the
caller.  One advantage of that is that it would guarantee the behavior
with --no-arg etc is going to match exactly.

I prefer this OPT_STRVEC approach nonetheless.  Can the
parse_opt_strvec and parse_opt_string_list functions get comments
pointing to each other as an alternative way to encourage that kind of
consistency?

nit: this should be OPT_STRVEC

Thanks,
