So while implementing this I realized it will not fly. At ARGV level it is impossible to tell apart "--domain" and "--domain ".
But it is not impossible to tell apart '"--domain"' (one arg) and '"--domain" ""' (two args). If you have trailing whitespace, then tack on an empty argument.
But the difference is important, because in the first case we want to offer list of all --options, while in the second case we want to call the --domain completer.
Yes, the difference between one argument and two is significant - the completion should always be done on the last argument, but the last argument needs to be the empty string if it is not in the middle of a word. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
