Errors are said in words, and a refusal names what it takes

A failure read `Del k|j: InvalidArgument`, `Kill: NoSuchCommand`, `ill-formed control message`, or nothing at all. reportError now spells an error's name as words, and the refusals name their accepted forms: pty/ctl lists its verbs, a flag file takes 1 or 0, a setting word takes on or off, Del takes k, j or nothing, Repl takes - or a language. Kill with nothing to stop says so, /focus says pane, a Look that found nothing says no match, and pty/run on a command pane says it is not a shell. A ctl write's failure has room for the Repl list and is cut between words, the Repl word at a character.
