If you try
%%%%%%%%%%
\version "2.19.47"
{
  1-\tweak control-points #'((0 . -5)(1 . -5)(5 . -5)(6 . -5)) ( 1)
}
%%%%%%%%%%
you see that the slur stencil procedure can produce a flat line (well, 
kind of, with the rounded sandwiching applied), so it’s possible to use 
this compoundSlur code with flat segments. I don’t know what you mean – 
do you mean ‘Novello-style’ moveable-type-like slurs with a rounded 
beginning, a long flat middle segment, and a rounded ending?

It sure does, and I thought that this is not a problem or in the 
contrary preferable because an engraver might have done the same, as in 
writing with a quill, so the curve naturally has these ‘bottlenecks’.
