[pkg-gnupg-maint] compatibility change which is worth to be included

[NIIBE Yutaka]

Hello,

My OpenPGP key in keyserver(s) have a subkey of ECC, and it caused a
trouble in Debian keyring.  I think that each time it got my key from
some keyserver for update, the subkey was added every time, although it
was already there.

It was fixed in the upstream for 1.4, 2.0 (and 2.1).

Fix in GnuPG 1.4:

    http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=commit;h=04667cabef2d6aaa214b288482bb902c891893a5

Fix in GnuPG 2.0:

    http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=commit;h=43429c7869152f301157e4b24790b3801dce0f0a

If 2.1 will be more popular and people will start to use ECC, it will
be good for gnupg package (1.4 series) in Debian to have this fix.
Perhaps, even for Jessie.
