Dear community,
I think the snippet of my last example was too large, so probably
nobody could see the basic problem that is:
How can I have a textspanner that ends with an arrow over a line break?
Here is a much shorter snipper to illustrate my problem:
\version "2.12.2"
\relative c'' {
\override TextSpanner #'bound-padding = #1.0
\override TextSpanner #'style = #'line
\override TextSpanner #'(bound-details right arrow) = ##t
\override TextSpanner #'bound-details #'left-broken #'text = ##f
\override TextSpanner #'bound-details #'right-broken #'text = ##f
\override TextSpanner #'(bound-details left text) = #"fof"
\override TextSpanner #'(bound-details right text) = #"gag"
\override TextSpanner #'(bound-details right padding) = #0.6
\override TextSpanner #'(bound-details right stencil-align-dir-y) =
#CENTER
\override TextSpanner #'(bound-details left stencil-align-dir-y) =
#CENTER
a8\startTextSpan gis a4 b b, \break
g'4 c\stopTextSpan c2
}
