Re: global staff-staff spacing fails in 2.13.46

[Trevor Daniels]

Hi Keith

I've pushed this patch, but isn't the immediately preceding text 
misleading,
in that it says,

"The following example demonstrates the two ways these alists can be
modified. The first declaration updates one key-value individually,
and the second completely re-defines the property:"?

But the first method fails on (at least) staff-staff-spacing.
