how do you deal with overlong lines?  that one is 80 characters, so
bibtex will split it.  how does \path deal with that?

personally, i would use \url from url.sty (which doesn't mind spaces
in urls unless you tell it to) or \url from hyperref.sty (which has
code to deal with this particular bibtex misfeature).
