Details:
I have noticed a couple of problems with the passphrase query.
First, decryption-only commands such as restore and list-current-files ask
for the passphrase twice, but this is unnecessary. It seems like only backups
should need this. Really only full backups need to ask twice for safety since
incrementals can validate against the encrypted archive, but that may make
expect scripts a bit more complicated.
Second, it would be helpful if the prompt went to stderr to handle the case
where the output is redirected, especially for list-current-files. This also
prevents contaminating the output of that command with the passphrase prompt
when used in a pipeline.
