[pass] [PATCH] Added metadata option to the show command

[Sebastian Verschoor]

Often. I forget the username or email that I used when I subscribed to
a service. I store it in the password-store using multiline format.  I
use `pass show` to find this information. However, this makes the
password vulnerable to shoulder surfing. I'd like an option where I
only display the username/email/other metadata.
