The C code already has hooks that make such a thing possible:
Just place a `wrap-prefix' property on the long-line which specify what
prefix to use when wrapping the line.

So all we need is a new minor-mode that uses jit-lock-register and then
sets up this property using something like fill-context-prefix.
