Description:
In German, we can use a hyphen to replace parts of words:
1) "be- und entladen" (instead of "beladen und entladen" [load and unload])
2) "Gesprächspartnerinnen und -partner" ("Gesprächspartnerinnen und Gesprächspartner" [female interlocutors and male interlocutors])

An the end of a line, the hyphen should not be seperated from the word. So it’s
1) "be-/line break/und " and
2) "und/line break/-partner".

But in the second case, LibreOffice Writer seperates the hyphen and "partner".

Steps to Reproduce:
1. Type a word that beginns with a hyphen (-) (like -partner)
2. Choose German as text language.
3. Add tabs or blank spaces befor the hyphen so that the line breaks. 

Actual Results:
The hyphen remains as last sign on the line, the word is on the new line. The line break is between the hyphen and the rest of the word.

Expected Results:
As the hyphen is part of the word, the line break should be before the hyphen.
