Most of the examples require { .. } iff the '..' consists of more than one 
element.

For example 
  \relative c' f
 is valid, but 
  \relative c' f f
is not. 

Could this behaviour be extended so braces could be used to clarify
command/argument boundaries in more complex cases, but with the
freedom to omit them (as now) if they were unnecessary?  That would
permit writing less ambiguous code if that were required without
breaking any existing files.  But I don't know how practical this would
be.
