[PUSHED] fdo#46223: Fix Presenter Console help screen layout

[Andras Timar]

Hi Gabor,

Good job, you fixed the bug for most of the languages. FYI, some
languages (scripts) neither use spaces to separate words, nor use
"normal" commas, so there might be some corner cases that are not
covered by your patch. I would say there is no need to overengineer
layouting of this window, affected languages can find out something,
e.g. put spaces manually into the translated string where they want
the line to break.

Pushed to master and libreoffice-3-5.

Best regards,
Andras
