So, I have a suspicion that the "=" in the description is fooling
"_arguments ... --" into thinking that the -a option wants an argument
of its own.  (I haven't really worked out what's going on in the help
text parsing in there, so I may be way off.)  You said before that you
have this completion problem only with the -a option, but do you by
chance also have it with the -d option, which also has an "=" in the
description?
