* verify.c (gpgsm_verify): Detect certs-only message.
2002-03-11 Werner Koch <wk@gnupg.org>
* import.c (gpgsm_import): Print a notice about imported certificates
when in verbose mode.
* gpgsm.c (main): Print INV_RECP status.
* server.c (cmd_recipient): Ditto.
* server.c (gpgsm_status2): New. Allows for a list of strings.
(gpgsm_status): Divert to gpgsm_status2.
* encrypt.c (gpgsm_encrypt): Don't use a default key when no
recipients are given. Print a NO_RECP status.
2002-03-06 Werner Koch <wk@gnupg.org>
* server.c (cmd_listkeys, cmd_listsecretkeys): Divert to
