Is there a "-----END PGP SIGNED MESSAGE-----" tag?

The armor line tags depend on the type of the message.  For example a
clear signed signature looks like this

  -----BEGIN PGP SIGNED MESSAGE-----
  Hash: SHA1
  
  Stay the curse.
  -----BEGIN PGP SIGNATURE-----
  Version: GnuPG v2.1.0-beta77 (GNU/Linux)

  yNwAn0caiuKpmJTiiutn+TqMlHsL4c66
  =3pzI
  -----END PGP SIGNATURE-----
  
The two armor lines are required by the special clearsigned format.  The
first BEGIN introduces the signed text, the second ends the signed text
and starts the signature, and the END ends all.  The details are, as
usual, in RFC-4880.
