Looks good so far.
I amended (and applied) your patch but have changed the following parts.
If you don't agree with them, please let me know. Commonly I don't change
a patch but I want to get these changes in and I think you'll agree with my
changes.
+"um die Auflösung entsprechend zu markieren und einzutragen,\n"
"oder benutze 'git commit -a'."
There are a couple of other parts in the file with the same pattern.
I've changed them in the same way.
#: wt-status.c:207
msgid "bug"
-msgstr "Fehler"
+msgstr "Bug"
I don't think that "Bug" is a better translation than "Fehler". It's not
really a German word. Most of the German people should
know what that means, but at least it's the same question
like the translation of terms like "commit". I removed it for now.
+"und benutze dann 'git add/rm <Datei>' \n"
I removed the whitespace before the line break.
I also changed "..packen..." to "...Packen...".
Thanks
