Comment #6 on issue 817 by percival.music.ca: Enhancement: new syntax for  
more flexible cresc/dim spanners
http://code.google.com/p/lilypond/issues/detail?id=817

James Lowe is currently working on documentation for:
  dynamics-context-textspan.ly
  dynamics-custom-text-spanner-postfix.ly
  dynamics-hairpin-length.ly
  dynamics-text-spanner-postfix.ly
as part of 989.  However, I'm not certain if these are absolutely necessary  
for 989 (after splitting off the post-2.13 stuff into 1217).  Also, I'm not  
certain if they should be snippets or part of the NR; I believe that he's  
working on getting them into the NR.

If you could add a bit more information, or at least reassurance, to:
  http://wiki.lilynet.net/index.php/Regtests
that would be nice.
