    Summary: Metalink download sends credentials

    Details: When curl is instructed to get content using the Metalink feature, and a user name and password are used to download the Metalink XML file, those same credentials are then subsequently passed on to each of the servers from which curl downloads or tries to download the contents from. Often contrary to the user's expectations and intentions and without telling the user it happened.
