This patch avoids several silly warnings, and fills $res->status_line with something useful
in case your FTP server babbles some text message without a leading response code.
Seen from ftp.opensuse.org:
connect(3, {sa_family=AF_INET, sin_port=htons(21), sin_addr=inet_addr("195.135.221.134")}, 16) = 0
read(3, "This server is busy, please try again later or any of my mirrors: http://download.opensuse.org\n\n", 1024) = 96
Note the missing "500 " before "This".
Command line ftp clients handle this gracefully, so should we.
With this patch, LWP clients see a status_line of "500 This server is busy, ..."
