Quotes around \consists argument?

[Jean Abou Samra]

Folks,

See 
https://gitlab.com/lilypond/lilypond/-/merge_requests/1323#note_921986589

The CG mandates quotes around the argument of \consists.
(https://lilypond.org/doc/v2.23/Documentation/contributor/lilypond-formatting)

I find that odd, since the quotes are unnecessary, and there are lots
of other places where quotes could be used but aren't in practice:

\new Staff                not  \new "Staff"
\override NoteHead.color  not  \override "NoteHead"."color"
\repeat volta             not  \repeat "volta"
\change Staff             not  \change "Staff"

OK to drop that policy? I can easily make a patch to sed out all
existing occurrences if consistency would be desired.
