Mime multipart was designed for mail transport through systems where
lines get chopped, wrapped, characters get translated, etc.

It's less likely that HTTP even through proxies will mangled data but
there's a need for a reliable end-marker, I could see adding a new
Content-transfer-encoding. What else beside EOF (and the escape
character itself) needs to be coded with the escape character?
