Well, the "clear from context" is exactly the case for compressed
packets because the zip algorithm has its own length management.

Not if you give --openpgp or when the recipient uses a v4 key.  I used
the other method to implement the indefinite length packets before I
knew about the OpenPGP WG.

Exactly. I have suggested to write a wrapper which swaps the sequence.
