Hi,

good point. Can you use both music-cause and event-cause? This clearly
signals whether a file has been processed (if it uses 'cause, it hasn't 
been). I'm quite sure that there is Scheme code that accesses 'cause in 
a couple of places. Can you verify that you converted everything by 
grepping the sources (including .scm and .ly files).

will you be able to make this change smoothly, or should we wait for a 
big conversion step? If it can be done smoothly, please apply after 
2.9.12 is released.
