Thanks, I checked it before submitting the patch.

OKay, but the patch does not really change the output of
(url-encode-url "http://www.gnu.org#"), except the for trailing slash.

The point is: there is no point in adding it when it is not needed,
which is what the current code does.

Admittedly, this is not a bug, but a small discrepancy that makes bare
URLs looks weird/ugly.

Stefan, let me know if you're fine with the patch and if I can commit
this in trunk or on some other branch.

Thanks,
