It's something to do with the two scripts attached to a skip in

\divisioMaior's not really ideal either though; according to MusicXML
2.0, it should be a partial barline between the second and fourth
lines.  If I ever get round to moving ly:bar-line::print to scheme (as
Han-Wen suggested), it should be easy to implement this by changing
'bar-size.

There used to be a "none" type, but it was removed ages ago; I wonder
whether it would be worth reimplementing it somehow.

Indeed.

It's not worth adding the extra orderings, so it's justified to ignore
the warning.

Could you remove Slurs from melismaBusyProperties for this?
