automatically adjust bar numbers upwards

[Neil Thornock]

Hi all,
By default, it appears that bar numbers, in order to occupy their
horizontal space, will push measure content to the right if necessary.
 In the code below, the C that begins measure 2 begins some way into
the measure to allow room for the huge number 2.  This gets very ugly
in my orchestra score, where only 3 staves in the system have bar
numbers.

{
    \override Score.BarNumber #'break-visibility = #'#(#f #t #t)
    \override Score.BarNumber #'font-size = #7
    \override Score.BarNumber #'self-alignment-X = #LEFT
    c'''1 c'''4 c''' c''' c'''
}

I'd like the measure number to be offset upwards so as not to impact
horizontal spacing.  I can do it manually every time it occurs; but
I'm wondering if there's a way to automatically set some behavior
where the bar number moves itself up, rather than moving everything
else to the right.  (I assume this is Scheme-able?)

Thanks!
Neil
