Review request for Plasma.


Summary
-------

Instead of blindly inserting a <br> into the string, only do so if we have more stuff to add later that would justify inserting the <br>


This addresses bug 227929.

Diff: http://reviewboard.kde.org/r/3042/diff


Testing
-------

Backported my patch to 4.4 for personal use. I tested having no notifications, having a job running, and having a paused job plus a job running. Linebreaks are inserted properly, if there is more text to show afterwards.


Thanks,

Jonathan
