So, I learnt something new today! I'll revert the patch.
However, there are several examples, both in input/*/*
and in scm/define-context-properties.scm which set these
properties in Staff or Score. Should I change them as well?


Another feature that's slightly confusing is that
\score {
         \relative c''{
                c4 c4 c4 c4 }
        \paper{
                raggedright = ##t
                \context{
                        \Staff
                        whichBar = ":|:" }
        }
}

is equivalent to
\score {
         \relative c''{
                \set Score.barAlways = ##t
                \set Score.defaultBarType = ":|:"
                c4 c4 c4 c4 }
        \paper{raggedright = ##t}
}

(except for the initial bar line).
However, if in the first of these examples I set whichBar globally in
the Staff context instead, then the setting only applies at the
beginning of the score.
