[Bug 1381455] [NEW] Redundant whitespace echoed by /usr/lib/update-notifier/update-motd-hwe-eol

[Gertjan Zwartjes]

Public bug reported:

The latest update-notifier-common update 0.119ubuntu8.7, adds support
HWE end-of-life reporting through motd. However if there are no updates
to report, the /usr/lib/update-notifier/update-motd-hwe-eol script will
always output two empty lines. This is kind of ugly in the full motd
text when you log in to a server.

For instance:

Welcome to Ubuntu 12.04.5 LTS (GNU/Linux 3.2.0-69-generic x86_64)

The offending echo's are at lines 47 and 48 in update-motd-hwe-eol.
Commenting these out solves the problem. Note that when there are HWE
EOL updates to report the /usr/bin/hwe-support-status script (which is
called by update-motd-hwe-eol) will make sure there are whiteline
prepended and appended when there's stuff to report. At least, from what
I found by looking at that script.
