warning a verbose item and translatable. (From wk on stable branch) * sig-check.c (check_key_signature2): Made "no subkey for subkey binding packet" a verbose item instead of a !quiet one. There are too many garbled keys out in the wild. (From wk on stable branch) * filter.h: Remove const from WHAT. (From wk on stable branch) * progress.c (handle_progress): Store a copy of NAME. (progress_filter): Release WHAT, make sure not to print a NULL WHAT. (From wk on stable branch) * openfile.c (open_sigfile): Adjust free for new progress semantics. (From wk on stable branch) * plaintext.c (ask_for_detached_datafile): Don't dealloc pfx->WHAT. (From wk on stable branch) * seckey-cert.c (do_check): Issue the RSA_OR_IDEA status when the cipher algo is IDEA to make it easier to track down the problem. (From twoaday on stable branch)
