Perhaps combining this with a note in compsys.yo about this side effect
to _message and hence also of _arguments when displaying messages would
cover enough bases.  For _arguments the caveat is perhaps more what you
said early --- that it doesn't espect to be combined arbitrarily with
other forms of completion ("arbitrarily" because it does have ways of
returning control to the caller to take the next steps).
