In the version of ZWEI on system 44.3, with microcode 692, on LISP Machine Eight:
If you type Meta-X Ev In <Return>, edit-in-mini-buffer blows out trying
to RPLACD NIL, because *mini-buffer-command* is NIL.  This appears to be
completely reproducible.  I see that you are setting that variables if
it is non-NIL; I guess someone like the COMMAND-LOOP must be setting it
back to NIL or something.

It is a damned pain that control-Zing out of this error does not get you to
top level; it gets you to the minibuffer command loop, and it is not
at all apparent that that is what's happened.  It is extremely confusing
even to me.  In the old days I had a catch that only the top level command
loop caught, for just this sort of reason.  This should be fixed.
