Winston. You're right. There is no such thing in GNU find.

There is no such shorthand (documented). "-perm +2" will only match 
when the other / world write bit is set. It will not mach when the 
owner and / or group write bits are set and the other / world write bit 
is not. And so on, as my previous experiment showed.

Maybe you're thinking of a some other find--a non GNU version?
