Barlines are too thick

[Marnen Laibow-Koser]

Lilypond's default barlines are far, far too thick.  Acceptable barlines 
in engraved music should not be significantly thicker than staff lines. 
 Also, at high magnification levels, the top end of the barlines 
overshoots the edge of the staff line; the bottom end of the barlines 
may do this too.
