This allows other clients to insert headers in extra lines of text between the Subject and Body fields of the message, as discussed on the 24x7 mailing list. The PyBitmessage client was never able to meaningfully display multi-line subjects, so this does not break anything. The extra lines are thrown away and never stored anywhere, so this also protects against watermarking attacks.
PyBitmessage
Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs.
