Error in Manual?

[Jason Yust]

There seems to be an error in the manual (perhaps a hold over from older
version). I'm getting two problems on section 4.3.1 and elsewhere. This kind
of notation:

\override BarLine.stencil = ##f

gives me an error. I need to use 

\override BarLine #'stencil = ##f

instead, but a number of the examples use the dot. Also, the "\omit"
function is not recognized by my versions (was using version 12.4, but
updating to the most recent stable version has the same problem).
