Syntax highlighting of a new grob name

[Dan Eble]

I am trying to document \caesura in the Notation Reference.

I have just made the docs starting from a clean build directory.

I see that CaesuraScript is highlighted differently than other grob names in 
this text:

    \override Score.Script.color = ...
    \override Score.MultiMesaureRestScript.color = ...
    \override Score.CaesuraScript.color = ...

Can I do something to address this?  TIA.
