If you're using setuptools to do your PyPI access in pip, you are
indeed unescaping. ;-) setuptools.package_index does full HTML
entity decoding, including both named and numeric references, so XML
escaping (which is a subset of that) should be just fine.
Likewise, #2 should be fine as long as urlparse.urljoin produces the
correct result using the retrieved-from URL as the base URL. I
stress this because some web applications treat the urls "foo" and
"foo/" as if they were interchangeable, and for relative-URL
purposes, they are not. So, as long as PyPI handles this correctly
based on the URL that was sent by the *client* (rather than perhaps a
canonical URL the client "should have" sent), then that will be fine.
