New issue 2522 by k-ohara5...@oco.net: duration*0 considered harmful
http://code.google.com/p/lilypond/issues/detail?id=2522

The documentation sometimes uses zero-time spacer rests s1*0 as an  
attachment point for markup or articulations, when there is no note  
available for the attachment.

Setting the current duration to 1*0, however, can cause surprise if a user  
fails to reset the duration.
  { b'1\> s1*0\! }
  \addlyrics { la. }  % Should be "la.1"
In this case, no lyric is printed.  The behavior with current duration set  
to zero is unfamiliar, so it might confuse people.  Maybe it is wiser to  
avoid durations of zero in examples in the documentation.

Workarounds
0) use explicit durations as required
1) use empty chord <>, which has zero duration but does not change the  
current duration, in place of s1*0.
2) use alternate solutions instead of zero durations
  \new Staff { << { b'1 } { s2\> s4 s8 s\! } >> }
  \addlyrics { la. }
