Many of the markup commands which are affected by baseline-skip rely
on the procedure 'stack-lines' found in scm/stencil.scm.

In the attached file, I provide an alternate 'stack-lines' which will
produce the "strict" spacing I believe you are asking for.  It ignores
the heights of the lines when stacking them.  Thus, a baseline-skip of
0 would produce lines drawn directly on top of each other.

To use this redefined command with \justify, I needed to include the
definition of the latter (from scm/define-markup-commands.scm in the
.ly file.  (Otherwise, the redefinition won't have an effect.)

HTH,
David
