Why not use a modified glissando:

\version "2.13.28"

guide = #(define-music-function (parser location padleft padright shift) 
(number? number? pair?) #{
    \once \override Glissando #'bound-details #'left #'padding = #$padleft
    \once \override Glissando #'bound-details #'right #'padding = 
#$padright
    \once \override Glissando #'extra-offset = #$shift
#})

\relative c'' {
    \override Fingering #'staff-padding = #'()
    \guide #2 #1 #'(0 . 1.4) <b-1>2\glissando <c-1>
}
