This line was a replacement for the following block originally in the Debian
maintainer script:

- # Stop squid3 daemon and remove init script links
- #
- if test -x /etc/init.d/squid3 ; then
- invoke-rc.d squid3 stop
- update-rc.d squid3 remove >/dev/null
- fi

If the 'update-rc.d squid3 remove' call has been removed now in Debian, we
can also drop this from the Ubuntu delta. This was all upgrade handling
from the old squid3 init script, which is obsolete now as of 16.04.

At this distance, I don't recall a specific rationale for removing that bit.
I don't know of any reason that it would cause a problem. At that point I
was trying to clear out everything that wasn't needed in order to make the
maintainer scripts comprehensible.

I doubt it's worth forwarding this bit up to Debian as a discrete unit. In
practice, all of this migration code ought to be dropped entirely in Debian
following the next stable release, and should already be no-op code in
Ubuntu post 16.04.
