Comment 1 for bug 142814

I think there are two usecases:

1) You are logged in as Manager to perform some copy operations
   for maintenance. Then the required behaviour is to do not
   change the ownership

2) You are logged as "normal" (but not as Manager) and you
   have the permission to copy files around. In this case
   your usecase might be wishful to be supported.

But I have no idea to bring these policies together without
breaking the existing behaviour.
