This is new with 15.0 i believe:

15.0:

router#sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, + - replicated route

12.4T

router#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

 Have you been playing with JUNOS lately? :)

Anyway, keep in mind that most-specific routing always wins. It's a way
of making sure that nobody else injects a route in that may mess up your
reachability. Even if you have a "C"onnected route on an interface
(AD=0), learning a more-specific route (/32 or whatever) will take
precedence over that. And Cisco's "thinking" never accounts for the
actual directly-attached IP address but rather sees it as part of the
larger group.
