Actually, making it a function returning a String would be sufficient (and a
definite improvement). Its probably going to be a less efficient solution than
the buffer-length procedure though. That would probably put off a lot of people.
But it is rare that I'm doing I/O and sweating a few extra cycles (the wait for
the disk or the typing user is going to swamp most other considerations).

Martin Carlisle had a good solution for this, which is posted at AdaPower at
http://www.adapower.com/adacode.html. It uses recursion, but I don't think the
stack impact is much more than 2n where n is the string size.
