Auto correction does not want me to comment out a line.

My goodness, this is tough to set up. I managed to... but still had to return to Frescobaldi, because IDK what VSLilypond does. E.g., every time I comment out a line inside /book (\bookOutputName "Partitur_Title") with %, then save. The plugin instantly removes the %.
I wanted to remove the manually set output name because the hyperlinks in PDF preview don't work. Maybe because it expects same name of .ly and .pdf file.
