Well, you wrote "in the code above", though I posted two different
codings. Which one do you refer to?

(1)
The first was meant to illustrate the current default behaviour, i.e.
keep-inside-line is #t
See the attached files.
keep-inside-line-01.ly is the current default
keep-inside-line-02.ly unsets keep-inside-line
Outcome of both is as I would expect.

(2)
The second [with \addScore #(+ 64.25 0.00)] points to a possible bug,
which may occur under certain circumstances.
Ofcourse there you can expect strange behaviour, this code is _meant
_to spot it.

Don't know, never tested.
Though it does not make much sense to set keep-inside-line differently
for PaperColumn and NonMusicalPaperColumn, imho.

Btw, you can make them visible with:

\layout {
  \context {
    \Score
    %% Enable only one, too confusing otherwise
    %\override PaperColumn.stencil = #ly:paper-column::print
    \override NonMusicalPaperColumn.stencil = #ly:paper-column::print
  }
}

IR says:
Function: ly:paper-column::print
    Optional stencil for PaperColumn orNonMusicalPaperColumn. Draws
the rank number of each column, its moment in time, a blue arrow
showing the ideal distance, and a red arrow showing the minimum
distance between columns.


Cheers,
