[CM] Snd: getting a prompt on stdout

[bil at ccrma.Stanford.EDU]

I added stdin-prompt to Snd, and tried it out briefly in the gtk 
version:

/home/bil/cl/ ./snd
(+ 1 2)
3
(set! (stdin-prompt) ">>>")
">>>"
>>> (+ 1 2)
3
>>> (exit)

I haven't yet tried it in emacs -- please let me know
of any problems.


(The sourceforge cvs version may be messed up --
I'm getting "transport endpoint" errors which I'll
need to track down).
