Some stencils will depend on the particular line break choices, some
not.

This code is incredibly hard to follow because the optimization problem
LilyPond has to solve leads to complex patterns of evaluating things
(and throwing a lot of them away).  And unfortunately the complexity is
distributed all over the place instead of having its code condensed into
one well-documented framework.

"well-documented" and "LilyPond code" rarely fit well into the same
sentence anyway.  But the code for this problem alone already makes it a
particularly bad area.
