vertical spacing problem when space is 0

[Nicolas Sceaux]

Hi,

A regression was introduced a few days ago regarding the spacing of
lines when next-space is set to 0 (this used to be fixed). On
ragged-bottom pages, the spacing is fine in spite of the programming
errors ("insane blocking force"), but otherwise it is wrong.

Example illustrating the problem:

\version "2.11.27"
#(define-markup-list-command (numbered-lines layout props num)
                             (number?)
  (interpret-markup-list layout props
   (do ((i 1 (1+ i))
        (lines (list) (cons (markup (number->string i)) lines)))
       ((> i num) (reverse! lines)))))

\markuplines \column-lines \numbered-lines #50
