New issue 2870 by address@hidden: \single needs user-level documentation and  
examples
http://code.google.com/p/lilypond/issues/detail?id=2870

In issue 2717, the command \single has been implemented for converting  
overrides into tweaks.  The issue desription contains a reasonably good  
overview, and as a music function, the function itself appears in the  
documentation with its elementary documentation string.

However, it should be featured more prominently in the sections concerning  
customization of properties as it forms a counterpart to \once in some  
respects.  It might make some sense tackling this together with documenting  
\no and \hide from issue 2859 currently on countdown, two music commands  
for creating overrides to make grobs disappear leaving no trace and and  
empty space behind, respectively.
