For very long headers returned from a web server rfc822.readheaders does not
correctly build the header.

The following patch fixes it in my situation but I don't know if I broke
anything else:

Example Header:

Location: https://www.website.com:443/tengah/Dpc/vContent.jhtml?page_type=3&PLANID=4&CONTENTPAGEID=0&TengahSession=312442259237-529/2748412123003458168/-1407548368/4/7002/7002/7004/7004

This ends up as

https://www.website.com:443/tengah/Dpc/vContent.jhtml?page_type=3&PLA

and the rest of the header (along with any headers following this one) get
returned as part of the message.
