Subject: [PATCH] Fixed "service" completion, thanks to John Hedges (Debian: #586210)

  The patch makes it safe even when every file in /etc/init.d/*
  has a proper completion (unlikely, but seems like it happened).

  Thanks to John Hedges <john@drystone.co.uk> for the patch, slightly
  modified to make it more compact.
