Given a password stored in _path/to/secret_, requesting the password
_path/to_ will literally return `path/to`. This can lead to using
weak passwords by accident/mess up logic in code, based on the
state of the password store.
This is worked around by applying the same logic `pass` uses:
If a password was returned, check if there is a .gpg file it could
have come from. If not, treat it as missing.
