beginning-of-measure padding value?

[ Lilypond 2.11.12 ; Mac OS X 10.4.9 ]

Hello, all!

In recent versions of Lilypond, I find that the first element of  
every measure is generally too close to the preceding barline for my  
taste -- i.e., there isn't enough left-padding on the first note or  
rest or whatever (n.b., the spacing issue is especially egregious  
when the first item is an accidental, arpeggio, or other "note  
attachment").

Is there a single setting I can adjust to globally increase the space  
at the beginning of measures?

I tried BarLine right-padding and space-after type options, but they  
all left unwanted space after the last barline of a given system...
There's also a nice hint on the list which assists with the  
"attachments", but I'd prefer a global option.

Thanks,
Kieren.
