[plt-scheme] Second teeny little net/url bug

Thanks for the reports, Synx.  I encourage you to file them as bug
reports at bugs.plt-scheme.org (or using the Help menu in DrScheme);
that way we implementers get automatic notification, reminders, audit
trails, etc., and as the reporter you get updates as we make progress
on fixing these bugs.
