Re: Ends of barlines are hidden in staff lines. (issue 4809057)

[mtsolo]

Make sure to consider cases like:

\relative c'' {
  \stopStaff
  \override Staff.StaffSymbol #'line-count = #1
  \startStaff
  b1
  \stopStaff
  \revert Staff.StaffSymbol #'line-count
  \startStaff
  b1
}

I haven't tested it out to see if the result is meh, but if you think it
leads to a bad result, make sure to add a condition (like the color
condition you added) for barlines whose break direction is CENTER that
have different StaffSymbol grobs to the left and right.

Cheers,
