macro arglists

[hall@allegra.att.com (Bob Hall)]

I don't know whether this is a bug or a mis-setting of some
environment parameter on my part:
  - Typing space after a function application in a Fred buffer gets me the
    function's arglist printed in the message window, e.g.
         (cdr<space>    yields cdr's arglist
    [this is GOOD]
  - Typing space after a macro application, however, gets me two question
    marks, eg
         (when<space>     yields ??
    [this is BAD].

Is this because I don't have some parameter set right?  Or is this a bug?
(I'm using MCL 2.0b1p3.)
