Question about bracketifying rests

[William Rehwinkel]

Dear list,

I use the following stencil (which is derived the bracketify-stencil 
procedure from lilypond) to draw editorial brackets around rests.

The output looks very nice and more preferable for my use than using 
\parenthesize (mainly because it changes in size for quarter note 
rests). However, I would like to ask if it is possible to modify the 
\override command to have the brackets account for the dots after the 
rest? Perhaps a higher level stencil that draws the Rest and dots?

Unfortunately I had trouble finding the source code which handles 
\parenthesize in the lilypond repository, which probably could have 
helped me.

Thank you,
-William
