I'm curious.  Why would it be wrong for users to expect 'pts membership 
system:authuser' and 'pts membership system:anyuser' to list their 
membership assuming the caller had the necessary access rights?  My 
primary objection to the existing behavior is that these groups are 
special and end users / administrators must understand that they are 
special.   If an authorized user can obtain the membership list from 
'pts membership system:authuser@foreign' why shouldn't the same be true 
for 'system:authuser'?   If the concern is the cost of generating the 
result set, its no more expensive then executing 'pts listentries'.

In a private response to my original message someone wrote that their 
cell uses the output of 'pts membership' to generate the list of 
entities that have access to a file object given the assigned ACL.  This 
is a perfectly reasonable action to expect to work.  However, the 
generated list will be incomplete when 'pts membership system:anyuser' 
and 'pts membership system:authuser' succeed while at the same time 
generate empty output.
