Markuplines spacing broken: how to set a line padding?

[Nicolas Sceaux]

Hi,

What is the new way of setting the next padding and spacing of an  
individual line
(a markup line in that case)?

I am asking because there is a regression regarding markup lines: they  
used to be
densely spaced, with no extra space between lines, but now they are  
stretched,
which is not desirable.

The code setting the next padding and spacing of markup lines is in  
paper-book.cc:

if (scm_is_pair (scm_cdr (list)))
   {
     /* If an other markup is following, set this markup
      * next padding and next space to 0, so that baseline-skip
      * only should be taken into account for lines vertical
      * spacing. */
   ps->set_property ("next-padding", scm_double2num (0.0));
   ps->set_property ("next-space", scm_double2num (0.0));
}

Reading the new vertical spacing code, I cannot find what properties  
should be used
there.

The following example demonstrates the problem:

\version "2.13.6"
\paper {
   ragged-last-bottom = ##f
}
#(set-default-paper-size "a6")
\markuplines {
   \column { A B } C D E
}
