If you have some hosts on your ethernet which have long names, rwho will
quit after the first user whose hostname:ttyname string is longer than
22 characters.
After the table of all users is built, it is sorted. Then there is a
"for" loop to determine the longest hostname (to make the output table look
nice). The next "for" loop prints out each user entry. The first thing done
in this loop is to define a character buffer "buf[22]" for the hostname
and tty the user is on. If this isn't enough, the counter for the loop, "i",
gets bashed (set to something very large) and the loop terminates. Just
increase the size of the buffer (I used 50).
