Merge branch 'es/test-gpg-tags'

A test for tags has been restructured so that more parts of it can
easily be run on a platform without a working GnuPG.

* es/test-gpg-tags:
  t6302: skip only signed tags rather than all tests when GPG is missing
  t6302: also test annotated in addition to signed tags
  t6302: normalize names and descriptions of signed tags
  lib-gpg: drop unnecessary "missing GPG" warning

-	say "You do not seem to have gpg installed"
-else

+then
 	# As said here: http://www.gnupg.org/documentation/faqs.html#q6.19
 	# the gpg version 1.0.6 didn't parse trust packets correctly, so for
 	# that version, creation of signed tags using the generated key fails.
