This sounds like a good idea. Probably the arrow drawing should be done
by the line-interface code, because arrows are a generic thing to have 
on lines.

If in Scheme, simply return the stencil. For C++ examples, see any 
print function.

I'm not sure it will work. There is padding (bound-padding property) 
between the text and the line,
but you could give it a try.
