[PATCH] Add docstring support to def-grace-function

[Patrick McCarty]

Hello,

This patch reworks def-grace-function so that it inserts the
docstring, if defined, into the template for define-music-function.
If the docstring is not defined, the unquote-splicing strips the empty
list from the template.  All further processing is left to
define-music-function.

Will this work?  I've tested it with the acciaccatura function.

Thanks,
Patrick
