HostFileNameParser fails extracting user info
---------------------------------------------

                 Key: VFS-88
                 URL: http://issues.apache.org/jira/browse/VFS-88
             Project: Commons VFS
          Issue Type: Bug
         Environment: any
            Reporter: Vincentas Vienozinskis
            Priority: Trivial


class org.apache.commons.vfs.provider.HostFileNameParser fails to extract user infomation from uri such as :

ftp://user@somecompany:userpassword@sompny.site.com

Note that 
User name : user@somecompany
Password : userpassword

As above uri is valid it should be parsed without exceptions. To fix this first ':' should be found instead of looking for '@' sign:

fixed method :

    /**
     * Extracts the user info from a URI.  The scheme:// part has been removed
     * already.
     */
    protected String extractUserInfo(final StringBuffer name)
    {
        final int maxlen = name.length();
        
        // First look for user info separator ':' then for '@'
        boolean separatorFound = false;
        for (int pos = 0; pos < maxlen; pos++)
        {
            final char ch = name.charAt(pos);
            if (ch == ':') {
                separatorFound = true;
            }
            
            if (ch == '@' && separatorFound)
            {
                // Found the end of the user info
                String userInfo = name.substring(0, pos);
                name.delete(0, pos + 1);
                return userInfo;
            }
            if (ch == '/' || ch == '?')
            {
                // Not allowed in user info
                break;
            }
        }

        // Not found
        return null;
    }
