* Merge from Debian unstable, remaining changes: (LP: #609634)
  - debian/init, debian/fetchmail.postinst: don't stop fetchmail in
    runlevels [06], the default 'killall' handler should be sufficient
    because fetchmail writes are properly completed before telling the
    server it's ok to delete.
