Now all is clear

The important thing is that one can make things work as it should creating

   umb1 with siblings listA listB
   umb2 with siblings listA listB listC

this is equivalent to umb2 = umb1 + listC (which won't work). Since the 
definition is done only once there is no different effort required in 
setting up things with nesting or with flat one-level arrangement.

The MUA could not have done that since it was unaware of the addresses 
(they were just list members). I verified (outside of mailman) that it is 
our MTA (sendmail) which does that, and it does it while sending. 
Subaddresses are preserved in the header if they were included (true for a 
"plain" sending, not true for a mailman sending). Since we use the same 
sendmail.cf on all our machines, this is fine for us.
