Use menu behavior for completion of switches

We already use the menu behavior in complete_command_name(); let's do
the same for switches, since we can complete all valid inputs and
it can save a Tab key in some scenarios.

CommandManager::complete is fairly complex. We can't expect callers
to add the menu bit when appropriate, so we currently do it here.
