Hi!

Dict protocol escapes you newlines. You are expected to de-escape them
yourself.

Following escapes are done, you can de-escape them with your client.

\x00 => \x10
\x01 => \x11
\t => \x1t
\r => \x1r
\n => \x1n

The change has been made to avoid breakage if newlines or NULLs are
injected into the data.
