Re: Invalid overrides in ly/gregorian.ly?

[Juergen Reuter]

Hi, all!

The horizontal placing of breathing signs in Gregorian Chant is anyway 
somewhat broken.  Looking e.g. at the "Sanctus, Sanctus, Sanctus" 
example in "2.8.4 Typesetting Gregorian chant", the distance for the 
second divisio minima (after the second "Sanctus") is fine, while the 
distance for the other two divisiones minimae is too wide.

I suggest the following: If removing the extra-X-extent from 
gregorian-init.ly does not increase the distance between the breathing 
sign and the preceding note (particularly the distance after the second 
"Sanctus"), then please remove it without replacement, since the minimum 
distance looks ok and the other bad distances can not be fixed by a 
constant extra extent anyway.  For double-checking, you should also ensure 
that removing the extra X extent has no visible impact on the "Salve, 
Regina" example at the beginning of chapter 2.8.

Many thanks & greetings,
Juergen
