Make nsFileSpecMac tough enough to deal with a Unix-style path with two or more forward slashes that are right next to each other; e.g., foo//bar/baz.html. Previously, it would convert this to foo::bar:baz.html, which is the Unix equivalent of foo/../bar/baz.html. Oops. Anyway, this keeps Mac from crashing on startup.
