Added two new functions, lsigned_already() and revoked_already() that check whether a key has been locally signed or revoked respectively during --populate. If the key is already signed or revoked, it is quietly ignored. Suggested-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Matthew Sexton <wsdmatty@gmail.com> --- v2. (ACTUAL v2.) Previous email was erroneous, I attached the wrong patch. Corrected some inconsistencies.
