Hmm. It can have URL-encoded parts (so we must decode when parsing), but
the more important question is whether the decoded version can have
parts that _need_ to be URL-encoded.  And I think the answer is no,
after double-checking the RFCs (i.e., hostnames cannot contain any of the URL
reserved characters). So quoting would be a no-op, and we can skip it.

Anyway, your later patch ends up removing this chunk of code, so I think
we can forget the issue entirely.
