    This tests for edge cases in url.URL's parsing algorithm. Most of

    these aren't useful for documentation purposes, so they aren't

    part of the class's doc tests.

    Query strings and fragments:

    >>> url('http://host/a?b#c')

    <url scheme: 'http', host: 'host', path: 'a', query: 'b', fragment: 'c'>

    >>> url('http://host/a?')

    <url scheme: 'http', host: 'host', path: 'a'>

    >>> url('http://host/a#b#c')

    <url scheme: 'http', host: 'host', path: 'a', fragment: 'b#c'>

    >>> url('http://host/a#b?c')

    <url scheme: 'http', host: 'host', path: 'a', fragment: 'b?c'>

    >>> url('http://host/?a#b')

    <url scheme: 'http', host: 'host', path: '', query: 'a', fragment: 'b'>

    >>> url('http://host/?a#b', parse_query=False)

    <url scheme: 'http', host: 'host', path: '?a', fragment: 'b'>

    >>> url('http://host/?a#b', parse_fragment=False)

    <url scheme: 'http', host: 'host', path: '', query: 'a#b'>

    >>> url('http://host/?a#b', parse_query=False, parse_fragment=False)

    <url scheme: 'http', host: 'host', path: '?a#b'>

    IPv6 addresses:

    >>> url('ldap://[2001:db8::7]/c=GB?objectClass?one')

    <url scheme: 'ldap', host: '[2001:db8::7]', path: 'c=GB',

         query: 'objectClass?one'>

    >>> url('ldap://joe:xxx@[2001:db8::7]:80/c=GB?objectClass?one')

    <url scheme: 'ldap', user: 'joe', passwd: 'xxx', host: '[2001:db8::7]',

         port: '80', path: 'c=GB', query: 'objectClass?one'>

    Missing scheme, host, etc.:

    <url path: '://192.0.2.16:80/'>

    >>> url('http://mercurial.selenic.com')

    <url scheme: 'http', host: 'mercurial.selenic.com'>

    >>> url('/foo')

    <url path: '/foo'>

    >>> url('bundle:/foo')

    <url scheme: 'bundle', path: '/foo'>

    >>> url('a?b#c')

    <url path: 'a?b', fragment: 'c'>

    >>> url('http://x.com?arg=/foo')

    <url scheme: 'http', host: 'x.com', query: 'arg=/foo'>

    >>> url('http://joe:xxx@/foo')

    <url scheme: 'http', user: 'joe', passwd: 'xxx', path: 'foo'>

    Just a scheme and a path:

    >>> url('mailto:John.Doe@example.com')

    <url scheme: 'mailto', path: 'John.Doe@example.com'>

    >>> url('a:b:c:d')

    <url scheme: 'a', path: 'b:c:d'>

    Non-numeric port:

         path: 'foo'>

    Bad authentication credentials:

    >>> url('http://joe@joeville:123@4:@host/a?b#c')

    <url scheme: 'http', user: 'joe@joeville', passwd: '123@4:',

         host: 'host', path: 'a', query: 'b', fragment: 'c'>
