restore on -CURRENT incompatible with 5.3 dump tapes

[Kent Hauser]

Hi,

I just found that my -CURRENT system won't read dump tapes from my 5.3 system.

After reconfirming the tape was good on the 5.3 system, I copied "restore" 
from the 5.3 system, installed the compat5x port, and it read the tape fine.

I'm not sure if "restore" or the tape driver changed. I *am* able to read dump 
tapes made by the -CURRENT system with the -CURRENT restore. The tape drive 
is a DAT72 SCSI drive with an adaptec 29160 interface card.

Thanks, Kent
