I've got a piece of music that has a dotted bar and a (hidden) time

I know I could explicitly set the bar number to the new correct number
(calculated number minus one) but is there a way of subtracting one
from the existing bar number?
Probably less than pretty, but here you go:
--------------------------------------------------------------------------------
{ \repeat unfold 40 c4
\applyContext #(lambda (c)
(set! (ly:context-property
(ly:context-find c 'Timing)
'currentBarNumber)
(1- (ly:context-property c 'currentBarNumber))))
\repeat unfold 40 c4
}
Thanks David. Took me a while to work out why it was taking 4 off my
measure numbers, but then I realised it must be done once per score, not
once per staff. (I'm autogenerating the lilypond code and so it was putting
the decrement code into each staff's output - I've fixed this, as you can
see).
