Yes, this is intended behavior. The reason is that the --edit-key
menu is to see and manipulate what is really on the key. A
revoked/expired photo ID shows up with a "[revoked]" or "[expired]"
just like a textual user ID would.

PGP 6 doesn't have any notion of a revoked user ID. It treats revoked
user IDs as unrevoked.

This is in fact how the --list-keys photo code works now, and if you
do "--show-photos --list-keys", you get the semantics you want.
- --list-keys does not display expired or revoked user IDs unless
- --verbose is set, and that holds for both textual and photo IDs.
