Aucbvax.300 NET.v7bugs utzoo!duke!vax135!ucbvax!mark Tue Aug 12 01:52:23 1980 col There is a bug in col as distributed which causes garbage sometimes at the end of outputs, such as /usr/doc/uucp/implement. The procedure "main" ends in "return 0" rather than "exit(0);". Changing it to exit makes the problem go away. The bug was exhibited on a Vax running Berkeley Unix and might not show up on some other systems, depending on their runtime startup routine.
