Description of problem:
Removing a user will remove also remove their group if they are the
only member of that group. This should either be disabled or the user
should be prompted if they want this to happen. Whilst it makes sense
for "private groups", it does not necessarily make sense for standard
groups.


Version-Release number of selected component (if applicable):
redhat-config-users-1.2.4-1

How reproducible:
absolutely.

Steps to Reproduce:
1. Create a group "transient"
2. Create a user (non-private group) and change their primary group to
"transient"
3. Delete the user.
  
Actual results:
The group "transient" goes too.

Expected results:
The group stays.
