Comment #10 on issue 2858 by [email protected]: Document \shape music function
http://code.google.com/p/lilypond/issues/detail?id=2858
The current \shape works nicely
{
\shape RepeatTie #'((-2 . 1.5)(-1 . 3 )(0 . 3 )(1 . 1.5))
b1\repeatTie }
It is too long to use as a tweak, without making the input harder to read,
and too valuable to users to complicate with an optional argument.
