I want to avoid using a list: that's the main purpose of my question :)

In my lilypond.lang file all these three elements are defined, so that 
they are supposed to have their own highlighting: \markup and {} are 
bold black, #... is kind of brown. But if I use the environment pasted 
above their highlighting is overridden.

I attach the current version of the files.
As you can see, I wrote a list for markup_command, but this is not much 
efficient because some \commands should be highlighted as markup 
commands only if they are inside a \markup{} block (for example, \override).
I chose to put in the list only the \commands specific of a \markup 
block, but if I could make this "conditional highlighting" work it would 
be much better (for a number of reasons).

I'll be off for a week. I hope to finalize it as soon as I'm back.
If you have any advice in the meanwhile, I'll be happy to hear :)

Thanks,
Federico
