It should...

Rack1R1#sh ip ospf nei
Neighbor ID Pri State Dead Time Address Interface

150.1.4.4 1 FULL/DR 00:00:33 155.1.146.4 Ethernet0/0

Rack1R1#sh ip ospf int
OSPF_VL0 is up, line protocol is up
  Internet Address 0.0.0.0/0, Area 0
  Process ID 1, Router ID 150.1.1.1, Network Type VIRTUAL_LINK, Cost: 10
  Configured as demand circuit.
  Run as demand circuit.
  DoNotAge LSA allowed.
  Transmit Delay is 1 sec, State POINT_TO_POINT,
  Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
    oob-resync timeout 40
    Hello due in 00:00:07
  Index 2/3, flood queue length 0
  Next 0x0(0)/0x0(0)
  Last flood scan length is 1, maximum is 1
  Last flood scan time is 0 msec, maximum is 0 msec
  Neighbor Count is 1, Adjacent neighbor count is 1
    Adjacent with neighbor 150.1.4.4 (Hello suppressed)
  Suppress hello for 1 neighbor(s)

IOS Version 12.2(15)T14.

I believe in previous versions IOS did not show this.
