I do not like to rely too heavily on what zlib compression's
beginning of stream looks like.
I think the new format can be deflated new header (fully
synched) followed by deflated payload.
So the sequence unpack-sha1-header followed by parse-sha1-header
would notice we are dealing with new format and reinitialize the
deflator at the point where the header deflator left off.
Wouldn't that work?
