Regression: Interrupted extender line, figured bass

[Mats Bengtsson]

Hi,

The following example shows a regression compared to version 2.12. It 
produces two extender lines that were vertically aligned in 2.12 but are 
not aligned in version 2.13.49. I'm not sure if it worked by incident or 
if it was intended behavior in 2.12, and I can hardly recall why I used 
this specific construct when typesetting the piece two years back.

\version "2.13.49"

ext = {
  \once \set useBassFigureExtenders = ##t
}

\score{
<<
\new Staff \relative c' {
    \clef bass
    c2 c, ~ | % \break
    c4 c c2 |
  }
\new FiguredBass \figuremode{
<_!>1 \ext |
<_!>2 \ext <_!>2 |
  }
>>
}
