(confusing?)

"Lyrics are ignored for aftergrace notes."

The test verifies the statement; however, the rendered example  
appears to be a normal grace note tied to the second "c." Only the  
fact that the grace note is closer to the first "c" than the second  
gives it away. Perhaps the test could be expanded (or a second test  
added) to demonstrate that
"Lyrics are ignored for grace notes, including aftergrace notes."
