modern-cautionary accidentals

[Patrick Karl]

The discussion of Automatic Accidentals in the Chapter 1 of the Notation Manual says:

modern-cautionary

This rule is similar to modern, but the ‘extra’ accidentals (the ones not typeset

by default) are typeset as cautionary accidentals. They are by default printed

with parentheses, but they can also be printed in reduced size by defining the

cautionary-style property of AccidentalSuggestion.

I cannot find any reference to a “cautionary-style” property in the Internals Manual.  AccidentalSuggestion does have a font-size property, but 

\override AccidentalSuggestion.font-style = #-2

does not seem to have any effect on the size of the cautionary accidentals.

Also, the neo-modern-cautionary discussion does not mention the possibility of reduced size accidentals; wouldn’t the info under modern-cautionary also apply to neo-modern-cautionary.

Here’s a snippet for the neo-modern-cautionary case:
