Re: text spanner collapse

[Mats Bengtsson]

Looking at the implementation, I found the solution to your problem. It 
turns out
that the line is only printed if it's longer than the dash-period 
property, which
probably makes sense if the line is dashed but not otherwise. Anyway, this
property is set to 3.0 by default for TextSpanner objects, so you can use
\once \override TextSpanner #'dash-period = #0
to solve the problem.
