Mysterious. Copying from texts on a web page is always tricky. It could be a difference between the browser or operating system. I was using FireFox on Windows.
That it gives the error message means it does not recognize the first word as 'files'. Apparently there is some invisible layout instruction prefixed to it by the copying process. If I knew what it was I could make the Diagram resistant to it. It is likely a HTML tag (perhaps <pre> to indicate it was unformatted text). So perhaps I should strip everything up to and including the first > from any line that starts with < before trying to recognize the keyword.
