bar numbers at beginning of bar

[Paul Scott]

Hi,

12.2.1

When numbering all bars the default bar numbers seem to be at the end of 
the previous bar which is confusing to the reader.  When I use

\override Score.BarNumber #'self-alignment-X = #-1

to try to make these less confusing to the reader *sometimes* the music 
above the bar numbers is moved to the right which looks ugly.  Is there 
another way to move the bar numbers without moving the music?

Thanks,

Paul Scott
