Re: Fix Issue 1290 (issue3832046)

The new patch fixes the issue, but we can't yet use it in larger scores,
if we want to do that.

Whenever there is more than one staff in a system, and any non-zero
skyline-horizontal-padding, minimum_distance is computed reasonably for
the first and second systems, but not the third and later.  For a
2-staff system (with non-protruding bass clefs to make the math easier)
the patch computes minimum_distance
3.05, 7.33, 29.41, 29.38
as it adds four systems to a page.
