This option allows to export a secret key in GnuPG's native format.
Thus no re-encryption is required and further the public key parameters
are also authenticated if a protection passphrase has been used.

Note that --import is not yet able to handle this new mode.  Although
old version of GnuPG will bail out with "invalid packet" if a mode1003
exported secret key is seen.
