Hm … I thought Hairpins were done in Scheme completely and 
simple-hairpin using elbowed-hairpin was the default stencil. The 
default stencil makes two different hairpins at linebreaks (the first 
doesn’t grow to full height, the second starts with a gap):

{
  <>\< \repeat unfold 8 c'8 \break
  \repeat unfold 8 c'8
  1\< <>\!
}

But I was wrong,

#(define simple-hairpin
   (elbowed-hairpin '((0 . 0)(1.0 . 1.0)) #t))

is *not* the default and prints two similar hairpins at a break:

{
  \override Hairpin.stencil = #(elbowed-hairpin '((0 . 0)(1.0 . 1.0)) #t)
  <>\< \repeat unfold 8 c'8 \break
  \repeat unfold 8 c'8
  1\< <>\!
}

So all the linebreak cleverness seems to be done at C++ level …
