This should do it:
The full stop is "any character", and the plus sign lets it continue as far as humanly possible, within the current paragraph - so all the way to the end.
But don't use this if your byline may be longer than a single line! Then, because all text gets No Break assigned, it and everything after it gets stuck in Eternally Overset text. If this could happen, limit the No Break to a sensible maximum of characters (based on the available width). That should be something like this:
to keep no more than 20 (in this case) together.
That did the trick. Thank you! I can't wait to figure this stuff out.
I hope you never have a text like
bla bla < first > and < second > and so on > by yourselve
These should generally be the same on a running basis. I'll keep my eye out though. Thanks.
will give you a bit more security.
