Hi Jean,

The problem is that spacing/padding is often — and, to my eye, unpredictably — 
a nightmare, depending on which context the Bar_number_engraver is included in. 
If there was a way to guarantee a given padding above a system, I wouldn’t have 
been driven to such lengths of coding desperation…  ;)
