Notating bends

[Jim Long]

I was looking for the counterpart to bendAfter and found
that Lilypond does not define a 'bendBefore' function.

I located Valentin's workaround function 'bendStart' at

http://lilypond.1069038.n5.nabble.com/bends-before-notes-how-to-tp22214p22218.html

but it doesn't compile for me under 2.16.2:

GNU LilyPond 2.16.2
Processing `bendStart.ly'

bendStart.ly:27:15: error: GUILE signaled an error for the expression beginning

                      b8 a g fis e2 }

Two questions:

1) Is there an open feature request to add a \bendBefore
function to Lilypond, complementary to \bendAfter?

2) Meanwhile, is there a simple adjustment to Valentin's code 
at the URL above to make the workaround viable?

Thank you!

Jim
