Thank you very much for the solution. I searched, there is a bug report 
(issue?) submitted to google code page:
https://code.google.com/p/lilypond/issues/detail?id=2748

Another question, just curious about how to find the necessary 
information to solve such kind of problems? The information in LilyPond 
document is dispersed everywhere. What's the best way to learn those 
information?

Thanks again for your kind help.

Merry Xmas and Happy New Year.
