Thanks! This produces the following output with the wrong passphrase:

gpg --decrypt file.gpg
[...]
gpg: DBG: cleared passphrase cached with ID: ABCD1234567890
gpg: decryption failed: Bad session key

Then when I try to decrypt the file again I get reprompted for the
passphrase which is a huge improvement. If I had the chance to choose
I would prefer the same sort of UI as the private key or ssh key uses
when the wrong passphrase is entered (e.g., "Invalid passphrase;
please try again") but the change in your patch is definitely a huge
improvement.


Thanks again,

Doug
