Hi,
Here's the final fstat(1) patch which obeys the '-n' switch.
Inodes have a lot on info, so the output is very long. Please nit
pick on the code, including any style(9) violations you see.
Bakul, I really like your "stat -a" because the output is compact,
but it's not as readable. /me wonders if there's a happy medium...
-Paul.
