Thank you, Adam -- I didn't know about those.  I had searched for something 
like that before implementing my own, but I think I searched using the term 
"heading" or something instead of "outline", unfortunately, so I never found 
them.

Now that I know about `org-display-outline-path', the one improvement I'd like 
to make is to enable it to display the headings with per-level indentation, and 
treat the first level specially (with an anchoring dot instead of a directional 
arrow), as my code did.  It's a lot more readable that way displayed in the 
minibuffer.

I suppose I would implement this by adding two new optional arguments to 
`org-display-outline-path':

  * `per-level-indentation': add a newline followed by <this string LEVEL-1 
times> in front of each SEPARATOR

  * `level-1-prefix': a special prefix for the first level's heading

...and make corresponding changes to the helper functions of course.  There 
should also be some way to access the new functionality interactively; the 
solution might be a new interactive wrapper function with its own name, or 
maybe some new variables?  I don't know; I haven't thought it all the way 
through yet.

Is there any interest in or opposition to such a patch?  I'd like to get a 
sense of whether it would be able to land in Org Mode before I start working on 
it.
