Indeed, these are more like Gnus's `M-i` (as well as a few other such
cases, PCL-CVS also had such prefix commands) in that they are somewhat
specific to a (set of) commands, whereas the other examples I mentioned
tend to be usable with "any" other command (tho they may end up doing
nothing in many cases).
