D267: 519_0001-Disable-importing-V3-or-older-public-keys-from-keyse.patch

Fixed patch; previous version included an extra translatable string. And lacked a
semicolon.

My one concern: Some programs in languages with implicit memory management
(Python, Vala) seem to use --list-packets to provide a 'detail view' of
keys etc. On 32-bit platforms, they'll try to allocate > 2^32 bytes of
memory to process a packet composition << 100 bytes; this will cause them
to crash.

Sure; will include GnuPG 2 in future. The instrumentation process is more
difficult becaus of its structure.

Thank you for the prompt response.

I am familiar with the standard. The only violation of a MUST I'm aware of is that
recipient and personal digest preferences are ignored for hashes with known attacks;
perhaps some of these changes cause GnuPG to behave badly in other cases?
