It may be legitimate to include the same file several times, even from
within itself.  So you need something like the "input stack size
exceeded" error message from TeX, and I can testify that people don't
tend to associate that error message with the actual cause.  I think
I've been tricked once myself.

So I would not expend all too much effort (of human and computer) on
improving the error message.  It will be quite hard _not_ to make this a
puzzler.
