I have a listowner who wants to know why the "delete" command ignores
the User-ID case.  eg:
 
>tell listserv delete sju-x [log in to unmask]
Ready; T=0.05/0.06 13:06:12
 
* The following users have been removed from list SJU-X:
*  [log in to unmask]
*  [log in to unmask]
*
* Notification has been sent to [log in to unmask]
* Notification has been sent to [log in to unmask]
 
Note that cc22dp0 and CC22DP0 had just been added by me for testing
purposes, so "add" knows the rules.
