encrypted password issue with gpg

When trying this:

`pass $(gpg --quiet --decrypt ~/.password-store/isync/gmail.gpg)`

it will not pop the master password and gpg exits with exit code 2, thus `fdm -kv fetch` fails to run

however, if I:
1) run `pass $(gpg --quiet --decrypt ~/.password-store/isync/gmail.gpg)`
2) type the master password
3) run `fdm -kv fetch`

then it will connect, authenticate, and fetch email.
