* options.h, g10.c (main), encode.c (write_pubkey_enc_from_list),

pkclist.c (algo_available), revoke.c (gen_revoke): Add --pgp8 mode.  This
is basically identical to --pgp7 in all ways except that signing subkeys,
v4 data sigs (including expiration), and SK comments are allowed.

* getkey.c (finish_lookup): Comment.

* main.h, keylist.c (reorder_keyblock), keyedit.c (keyedit_menu): Reorder
user ID display in the --edit-key menu to match that of the --list-keys
display.

* g10.c (add_notation_data): Fix initialization.
