Ok. I played a bit with your example files:

\version "2.18.2"
#(set-default-paper-size "a4" 'landscape)
\score{
        {
                c'1 c' c' c' c' c' c' c' c' c'^"default"( c''
                c' c'') c' c' c' c' c' c' c' c' c' c' \break

                c'1 c' c' c' c' c' c' c' c'
                \override Slur.after-line-breaking = #(lambda (grob)
                    (let* ((layout (ly:grob-layout grob))
                           (paper-width (ly:output-def-lookup layout 
'paper-width)))

                          (if (> paper-width 100) ;; !!
                              #{ \shape #'((0.0 . -2.0) (0.0 . 1.0) (0.0 . 0.0) 
(0.0 .
0.0)) Slur #}
                              #{ \shape #'(((0.0 . 0.0) (0.0 . 0.0) (0.0 . 0.0) 
(0.0 .
1.0))
                                           ((0.0 . 5.0) (0.0 . 3.0) (0.0 . 0.5) 
(0.0 .
0.0))) Slur #}
                          )))
                c'^"image of purpose"( c''
                c' c'') c' c' c' c' c' c' c' c' c' c'
        }
}

You have to change the value of 100 to your needs (I think lilypond
uses staff-spaces as units here).

HTH,

Marc

Thanks for your reply.

But, hmm..., my copy has no effect:

I've mistaken anywhere?

Probably not – I just copied your \shape calls into my function and did 
not check the visual output.

Perhaps someone else has an idea?

Marc

Although I've not change the threshold value, some effect should appear.

Thanks
