that's orthogonal to the issue and the target.  the OP wanted to upgrade "all 
packages" which is @installed.  if you want to rebuild when USE flags change, 
then use --newuse.  no target should imply different option behavior.

it works for me, but i'm using latest portage (the _alpha## stuff).  any 
proposed change would require an update anyways ...

i don't know about set behavior and the world file.  it would make sense to me 
that "world" would special case @system and @installed and not add it to 
@world unlike other sets (i know that other sets do get added to world).  Zac 
would know of course.
