Review request for Plasma.

Repository: plasma-workspace


Description
-------

While looking into https://bugs.kde.org/show_bug.cgi?id=343532 I noticed that wall sends message always starting with \n, but with our limited space, that makes no sense.

With this patch the text is first trimmed from whitespace at the beginning and end, then all \ns are converted to <br/> (as before), then the text replaces all remaining inner whitespace with single space and finally, if there are two new lines in succession, it turns it into just one.

The bug itself, which is about messages from wall not appearing in the popup, will only partially get solved by this as the popup is limited in max height, so it displays at most 3 lines of text and with wall first two lines are already taken, that leaves just one line for the actual message.

However these are persistant so they get saved in the notification history anyway.

Testing

Now I'm able to see the message sent with wall.


Thanks,
