Status of break-align-symbol vs. break-align-symbols

[Robin Bannister]

> 

Convert rule 2.11.23 replaces _any_ break-align-symbol and its symbol 
with a break-align-symbols list containing just that symbol.    
This is reported in the NEWS as a syntax change.   

So presumably break-align-symbols is no more than a generalisation
of break-align-symbol, simply catering for more than one symbol.    
But this interpretation does not tally with 
http://lists.gnu.org/archive/html/lilypond-devel/2007-05/msg00002.html


In define-grobs.scm 2.12.2 there are    
 - 11 grobs with break-align-symbol     
 -  2 grobs with break-align-symbols (BarNumber and RehearsalMark)     

This looks out of sync with convert-ly, 
but maybe the break-align code caters for a transitional phase?  


In the following case it doesn't:  
The custos trick in 
http://lists.gnu.org/archive/html/lilypond-user/2006-09/msg00467.html  
was not demonstrated there, but it works.   

The corresponding override currently in the LSR is ineffective.
