I guess it was lucky.

At the moment, no. If you can point to some zlib documentation that
explains what the 'x' on each output does (*), feel free to submit a
patch to the pickle implementations that documents (in a comment) that
letter as being reserved for this purpose; it seems no harm is done
doing so. Please submit that patch to sf.net/projects/python.
