Message 349917 - Python tracker

From RFC-1738:

hostname       = *[ domainlabel "." ] toplabel
domainlabel    = alphadigit | alphadigit *[ alphadigit | "-" ] alphadigit
toplabel       = alpha | alpha *[ alphadigit | "-" ] alphadigit
alphadigit     = alpha | digit

However:

py> urlparse('https://foo\\bar/baz')
ParseResult(scheme='https', netloc='foo\\bar', path='/baz', params='', query='', fragment='')

The hostname's BNF doesn't allow for a backslash ('\\') character, so I'd expect urlparse to raise a ValueError for this "URL".
