from hanging over barlines.

Hey all,

I'm abandoning the patch but not the issue.

The only way to solve this problem is to create a BarLineStub grob that has  
the same height as the bar line and has an extra spacing height from the  
pure-from-neighbor-interface.  Then, in separation-item.cc, only ever allow  
this grob to be part of a horizontal skyline on the left (to block  
accidentals) but never on the right.  Then, the accidental hang-over can be  
controlled by sliding this grob left from the BarLine.  Its X-offset from  
the BarLine can be controlled by a callback that pushes it slightly further  
back if there is lots of potential accidental hang-over but otherwise keeps  
it at the same horizontal position as the bar line.

This'll take some time & I won't be able to do it in the near future.  If  
there are any takers, I'd be happy to help out!  It is a great project for  
someone who is new-ish to development and would like to learn about  
horizontal spacing.
