need markup function for arrow at end of curve

[Kieren MacMillan]

Hi all,

Anyone with reasonable \path chops out there? I need a function that outputs a markup like this:

In a perfect world, the length, height, Y-direction, X-direction, and line thickness would all be parameters… but even one sample would be enough for me to riff on.

Thanks!

Kieren.
