[dev] netsted group problem with HEAD

[Todd Merritt]

I'm running HEAD and have run into a problem with nested groups.  If I 
have a group foobar and assign a permission to that group it works, but 
if I have a subgroup called foo, I can assign a permission to that 
subgroup and it reports that it successfully assigned the permission,  
but when I attempt to access something under that group I get a 
permission denied failure.  I'll go file a ticket, but thought I'd 
mention it here in case anyone else had run into it.

Thanks,
Todd
