PK_UID_CACHE_SIZE (set in ./configure).
* getkey.c (get_pubkey): When reading key data into the cache, properly
handle keys that are partially (pk, no UIDs) cached already. This is
Debian bug #176425 and #229549.
* compress.c (init_compress, push_compress_filter2): Do the right thing
(i.e. nothing) with compress algo 0.
* main.h, decrypt.c (decrypt_messages): Accept filenames to decrypt on
stdin. This is bug #253.
agent is to be used. Noted by Ingo Kl�cker.
(agent_get_passphrase): Inhibit caching when we have no
fingerprint. This is required for key generation as well as for
symmetric only encryption.
* passphrase .c (agent_get_passphrase): New arg CANCELED.
(passphrase_to_dek): Ditto. Passed to above. Changed all
callers to pass NULL.
* seckey-cert.c (do_check): New arg CANCELED.
(check_secret_key): Terminate loop when canceled.
* keyedit.c (change_passphrase): Pass ERRTEXT untranslated to
passphrase_to_dek and translate where appropriate.
* seckey-cert.c (check_secret_key): Ditto.
* keygen.c (ask_passphrase): Ditto.
* passphrase.c (agent_get_passphrase): Translate the TRYAGAIN_TEXT.
Switch the codeset to utf-8.
