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'
Parsing...
bendStart.ly:27:15: error: GUILE signaled an error for the expression beginning
here
\bend #
$argument
Unbound variable: $argument
bendStart.ly:27:14: error: wrong type for argument 1. Expecting integer, found
#<unspecified>
\bend
#$argument
bendStart.ly:36:22: error: error in #{ ... #}
\bendStart #-2 { g' }
b8 a g fis e2 }
Interpreting music...
Preprocessing graphical objects...
Finding the ideal number of pages...
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!

Re: bends before notes... how to?
Here is a new command : \bendStart
it needs two arguments :
\bendStart #number {ghostnote}
the ghostnote will not be printed; its only purpose is to specify the
placement of the bend sign.
%}
\version "2.16.2"
#(define (make-bend x)
(make-music 'BendAfterEvent
'delta-step x))
bend =
#(define-music-function (parser location delta) (integer?)
(make-bend (* -1 delta)))
bendStart =
#(define-music-function (parser location argument music) (integer? ly:music?)
#{ \hideNotes
\once \override NoteColumn #'X-extent = #'(0 . 4)
\cadenzaOn
\bend #$argument
\grace $music \cadenzaOff
\unHideNotes
#} )
\paper {
ragged-right = ##t }
\relative {
\bendStart #-2 { g' } b8 a g fis e2 }
