Ahh, this is cool.  Don't have the fancy colorization though.  Maybe 
because I have my font-lock stuff set to be just fonts instead of colors?

This works very, very nicely!  Thanks!  And the easiest workaround is to 
use :ABORT instead of ABORT, so no gratuitous errors if at top-level.  I 
think, but I'm not sure, that ilisp looks at the prompt.  I know, 
thought, that ilisp looks at lisp prints out about restarts to figure 
which restart to use.  There's a bug in ilisp about this too.

Yeah, but I find I still type things in directly to the listener.  If 
you have a listener in elisp, that would be ok.

I really appreciate your help in all this.  I'm now just about ready to 
start using SLIME instead of ILISP now.  :-)
