FWIW, I've always thought it was a wart that there wasn't a recognized
InvalidCommandId value. It was never pressing to fix it before, but
if LCR needs it, let's do so. I definitely *don't* find it cleaner to
eat up another flag bit to avoid that. We don't have many to spare.
Ideally I'd have made InvalidCommandId = 0 and FirstCommandId = 1,
but I suppose we can't have that without an on-disk compatibility break.
