[BUG] doveadm / mail-crypt: Error when setting new password for a user key

Dovecot version: 2.3.14

When setting a new password for a user key you have the option to prompt the user for the old and the new password, instead of providing them as parameters (using -N and -O instead of -n and -o).

However, running: doveadm mailbox cryptokey password -u user@domain -N -O

produces an error instead of prompting the user for the old and the new password.

The error is: password: option requires an argument -- 'O'

You can work around this by providing a dummy input for -O which seems to be properly ignored in the end, but it would be nice to not throw any errors since -O should not expect an argument.

Regards.
