from the man:
OpenPGP states that an implementation should generate v4 signatures but
PGP versions 5 and higher only recognize v4 signatures on key material.

Do you know, which pgp versions have difficulties with v4 data
signatures or is this refered to *all* versions up to PGP 8?

This option forces v3 signatures for signatures on data.
Note that this option overrides --ask-sig-expire, as v3 signatures
cannot have expiration dates. --no-force-v3-sigs disables this option.
So with --gnupg i cannot have an expiration date as with --openpgp or

And what is with combinations like
--openpgp --force-mdc
--gnupg --no-force-v3-sigs
Overwrites --openpgp/--gnupg the other options?
