No.... I guess I should fix the man page, and maybe the code :-(
In mdadm-2 we've added --bitmap= and use '-b' as a short version.
So sometimes -b takes an argument (--bitmap) and sometimes not
(--brief). So getopt is told that it takes an optional argument.
This explains the observed behaviour.
Possibly this was a mistake....
I would like it to take an argument in contexts where --bitmap was
meaningful (Create, Assemble, Grow) and not where --brief is
meaningful (Examine, Detail). but I don't know if getopt_long will
allow the 'short_opt' string to be changed half way through
processing...
At the very least, I can print a message if '-b' is being interpreted
as as --brief, but the option argument is present.
-a has the same problem (--add vs --auto).
I'll see what I can do,
Thanks.

Oh yes. That blank line gets filled with 'spares=' if there are
any spares, and =devices=' if --verbose. But I should remove it in
other cases. Thanks.
