R4778 XML import & line breaks
I will focus this question in this trunk forum as this is the future version.
XML import/export has recently received many updates and is getting very clean. However, one this which I didn't notice until now was the auto-linebreaking that was happening. Issue #12437: [trunk] R4754 MusicXML issues: keysig imports in first staff only dealt with keysig export/import and through that I noticed that some component of XML was auto-inserting linebreaks.
Now, I typically do set a line break about every 4 measures in my own scores, and so does the XML import. However, my question is why does it do this? It is a manual process to remove them if someone don't want them.
