`answer z` quotes `z`, a bare `name` says it names nothing, and `Repl klingon` is invalid (EINVAL), its message citing no doc path

A refused answer quoted the word `answer`, not the choice refused. A
`name` with nothing after it was an unknown control message. A Repl of
no such language failed EIO with a pointer into the reference; it now
says `invalid language` (EINVAL, here and through a mount) and how many
more there are. A builtin's failure that says invalid anywhere is
EINVAL, as 9ns reads it.
