I guess the best we could do now would be to make fd= and fds= synonyms
with both supporting either comma-separated or being specified
multiple times ?
It's particularly confusing in this case that fd= doesn't work with
queues=, because the user isn't trying to pass multiple fds, just
the one is fine.
