melismaBusyProperties: scheme syntax vs. lily syntax

[Simon Albrecht]

Hello everybody,

I just noticed that it’s possible to use the LilyPond symbol list/key 
list syntax when setting melismaBusyProperties. However, the doc string 
reads

"A list of properties (symbols) to determine whether a melisma is playing.
Setting this property will influence how lyrics are aligned to notes.
For example, if set to @code{'(melismaBusy beamMelismaBusy)},
only manual melismata and manual beams are considered.
Possible values include @code{melismaBusy}, @code{slurMelismaBusy}, 
@code{tieMelismaBusy}, and @code{beamMelismaBusy}."

Would we want to change the first code example to

@code{melismaBusy,beamMelismaBusy}

or otherwise suggest the new syntax?

Best, Simon
