New issue 2981 by address@hidden: Bugs with \set Staff.whichBar
http://code.google.com/p/lilypond/issues/detail?id=2981

Ben Rudiak-Gould reported here:
http://lists.gnu.org/archive/html/bug-lilypond/2012-11/msg00104.html

as follows:

The 2.16 documentation says that \set Staff.whichBar = "|:" "will create a
start-repeat bar in this staff only". What it actually seems to do in  
2.16.1 is
insert a start-repeat bar after every note in that staff until the end of  
the
score. I haven't looked at the code but I guess that it's clearing
Timing.whichBar even if whichBar was actually set in a different context.

The obvious workaround, \once \set Staff.whichBar = "|:", prints the repeat  
bar
correctly but then never prints any automatic bar lines in that staff until  
the
end of the piece. I think this may be a bug introduced by
codereview.appspot.com/4810042, which never unsets a \once \set variable  
even if
it was unset before.
