No, there is no such option.  Eventually we will add this but it needs
quite some work because we can't use the standard stdio printf for
some reasons (we need an emulation of funopen).

I wonder why you are not using gpgme - it takes care of all this and
listing the secret keys is the just a matter of:

  err = gpgme_op_keylist_start (ctx, NULL, 1);
  fail_if_err (err);
    
  while (!(err = gpgme_op_keylist_next (ctx, &key)))
    {
      /* Now check key flags or do whatever you want to do with that
         key.  E.g: */
      if (key->revoked)
	{
	  fprintf (stderr, "Key has been revoked\n");
          gpgme_key_unref (key);
	  continue
	}
      foo (key);
      gpgme_key_unref (key);
    }
  if (gpg_err_code (err) != GPG_ERR_EOF)
    fail_if_err (err);
  err = gpgme_op_keylist_end (ctx);
  fail_if_err (err);

This also allows to switch to X.509 keys with just one function call.
Further you automagically participate from newer developments, like
running gpg as a co-process.
