Apparently this applies to clefs also.. see Michael Lakes' recent posting on 
lily-user. My opinion is that in general, events that take no musical time 
(i.e. not even grace time) should be executed _before_ any grace notes in 
other contexts. This would include e.g. \set and \override as well, and an 
exception would of course be if the event explicitly occurs after a grace 
note, as in { \grace c8 \clef "G" c1 }. But e.g. in
<<{\grace c8 c1 } \\ {\bar "||" b1 }>>, the bar should come before the grace 
note.

This is just a suggestion.. Are there any opinions on this?
