Re: Unwanted space around cautionary accidental

[Valentin Petzel]

Accidental and AccidentalCautionary grob definitions differ in three ways, the 
Accidental grob has these three additional properties:

(extra-spacing-width . (-0.2 . 0.0))
(horizontal-skylines . ,(ly:make-unpure-pure-container 
ly:accidental-interface::horizontal-skylines))
(vertical-skylines . ,grob::unpure-vertical-skylines-from-stencil)

I know no good reason why these properties should differ, as the only 
difference between these grobs should be that AccidentalCautionary has 
parenthesize set to #t by default.

Anyway, since AccidentalCautionary is missing the property to calculate 
vertical skylines from stencil it will do so only from extent, which gives you 
higher skylines and thus also more required space.

Your problem is solved by doing
\override AccidentalCautionary.vertical-skylines = 
#grob::unpure-vertical-skylines-from-stencil

Cheers,
Valentin
