Overriding nested props using a list, aka less arm twisting for our French users ; )

[Neil Puttock]

Hi everybody,

We currently have the following syntax for reverting properties,

\revert Grob #'(list of nested props)

which is rather convenient when using bound-details.

Now we've recently had a few complaints about how cumbersome
overriding properties for spanners can be, so I thought it might be a
good idea to make nested overrides a tiny bit easier by also allowing
lists using \override:

\override DynamicTextSpanner #'(bound-details left text) = "foo"

Is anybody in favour of such a change?

Cheers,
Neil
