OK, but the server knows that if it has the whole body sent it has to listen to
new headers.

Oh, dit I forget to mention that I implemented escaping?

But that version had also a bug. So I implemented not only masking of
\[separator] but of all \ . Here an example:

Separator is n .
Packet 1: \
Packet 2: foo bar
Real sent: \\nfoo bar\n
Parsed to:
Packet 1: \nfoo bar

With the old implementation the first \\n would not be recognized as separator
but as masked separator.

So with masking all \ :

Separator is n .
Packet 1: \
Packet 2: foo bar
Real sent: \\\nfoo bar\n
Parsed to:
Packet 1: \
Packet 2: foo bar

So this should work now at all events.

ACK
