Yes, this is really irksome, but it's a problem with ordinary text spanners
too. They don't avoid text overlaps automatically. The only corrective
for the problem is setting minimum-length.
{
\override TextSpanner.bound-details.left.text = #"really long long text"
\override TextSpanner.bound-details.right.text = #"overlapped"
% gives 2 instances of strange error in 2.19.27; other versions?
% programming error: mis-predicted force, 108.120472 ~= 139.065846
%\override TextSpanner.minimum-length = 25
%\override TextSpanner.springs-and-rods = #ly:spanner::set-spacing-rods
c1\startTextSpan
c1\stopTextSpan
}
In order to get independent line lengths for the musical theatre example,
you'd have to use two spanners as you do above. I don't think \alterBroken
would work since minimum-length is set before line-breaking.
