2008-05-07 Werner Koch <wk@g10code.com>
* getkey.c (get_pubkey_byname): Fix nodefault case.
* gpg.c: New command --locate-keys. New options --with-sig-list
and --with-sig-check.
* keylist.c (locate_one): New.
(public_key_list): Add arg LOCATE_MODE and use locate_one.
* getkey.c (get_pubkey_byname): Fix nodefault case. Add option
RETCTX, change all callers.
(struct getkey_ctx_s): Add field extra_ptr;
(get_pubkey_end): Free it.
