Probably not a bug.  
I think the behavior of stretching lines near a forced-stretched line is
intentional -- to keep note-spacing locally uniform.  What newer versions
do to this example is just beautiful :

{c''1 \break
\repeat unfold 200 d''
}

The way the markup affects line-spacing behavior in 2.13.51 is odd,
but within the discretion we give to LilyPond.  If we need drastically
different line spacing on neighboring lines, then we have to take back
control with \noBreak
