sylpheed-port found this in their own §6 and it is in mine identically. I stated the pass condition as 'exit 0' but left the command silent, so a reader running it as written sees an empty line and cannot tell success from failure. Worse than a number without a pass condition, because there is no number. Now carries '; echo $?' and says why.
