• g10/delkey.c (confirm_deletion): New.

(do_delete_key): Confirm deletion of each individual key.

When asked to delete a key, gpg confirms the deletion once
no matter how many keys have been targeted for deletion.

Now it confirms the deletion of each individual key.

Given a temporary gpg home with primary and subordinate keys:

$ agent/gpg-agent --daemon --homedir $XDG_RUNTIME_DIR/gnupg-git
$ g10/gpg --homedir $XDG_RUNTIME_DIR/gnupg-git --batch --passphrase '' --default-new-key-algo 'rsa1024/cert+rsa1024/sign' --quick-gen-key test
$ SUBKEY=$(g10/gpg --homedir $XDG_RUNTIME_DIR/gnupg-git -K --with-subkey-fingerprint --with-colons | awk -F: '/fpr/ { print $10 }' | tail -1)

Attempting to delete keys should result in:

1. The correct secret key fingerprints being printed in the confirmation prompts.
2. The deletion of every secret key being confirmed if the key specification is not exact.
