Subject: [PATCH] gpg: allow import of previously known keys, even without UIDs
* g10/import.c (import_one): Accept an incoming OpenPGP certificate that
has no user id, as long as we already have a local variant of the cert
that matches the primary key.
--
This fixes two of the three broken tests in import-incomplete.scm.
