[Bug 1007094] Re: "gpg --clearsign" does not create the "-----END PGP SIGNED MESSAGE-----" tag

[Michael Bienia]

Citing http://tools.ietf.org/html/rfc4880#page-59:

| 7. Cleartext Signature Framework
[...]
| The cleartext signed message consists of:
|
|     - The cleartext header '-----BEGIN PGP SIGNED MESSAGE-----' on a
|       single line,
|
|     - One or more "Hash" Armor Headers,
|
|     - Exactly one empty line not included into the message digest,
|
|     - The dash-escaped cleartext that is included into the message
|       digest,
|
|     - The ASCII armored signature(s) including the '-----BEGIN PGP
|       SIGNATURE-----' Armor Header and Armor Tail Lines.

To my understanding the message ends with the signature armor tail line:
'-----END PGP SIGNATURE-----'

  Now, run gpg --clearsign pickles, creating pickles.asc. And then see
  its contents:

  raub at ubuntu86:/tmp$ cat pickles.asc 
  -----BEGIN PGP SIGNED MESSAGE-----
