Hello misc,
Here's a tiny patch for bin/mt/mt.c to allow the command "mt status" to
print current file and block numbers, like it does in most other Unixes.
The information was already available in struct mtget, so only two printf
lines was needed.
I have verified that the current file number is reported as expected using
a HP DAT72 USB tape drive.
