    Hi folks.

    I noticed that when you set :echo to nil in a
    presentation-to-command-translator definition, the command line (along
    with the often ugly argument object) don't show up at the interactor
    prompt.

    I also noticed that the command still goes to the output history,
    however, which causes the command to show up if one tries to get up
    the command history (ctrl-(meta)-y on Genera). I was wondering if
    maybe :echo nil should be changed to eliminate this, or if there is
    another way to do the trick.

You discovered :ECHO NIL, but didn't discover :MAINTAIN-HISTORY NIL.

Do I win any sort of bet for guessing that someone would ask for this sometime?
