In general I'm in favour of allowing most weird things as long as libcurl can
work with them "garbage in garbage out" style. But for CR specificly, I think
I'm starting to agree that by accepting them as legal characters within the
URL we only get very weird effects.

I would assume that if you try the same URLs to a http server, you'd get even
strange results as then libcurl would actually send the request with a
trailing CR on the request...

This said, I don't think that wget's behaviour is correct for curl either.
Translating it to %0d is plain wrong for curl. We either accept input or we
reject it, no smoothing over.
