Comment #1 on issue 2917 by address@hidden: Extend \keepWithTag to allow  
multiple tags
http://code.google.com/p/lilypond/issues/detail?id=2917

Since Nicolas' function works with either one argument or a list of
arguments, replacing the current definition of \keepWithTag (without s)
with his code seems the best way to go here.

Other music functions concerning tags should be changed, too, of course.
