Hi Basil and everyone,

I appreciate the shout but unfortunately can't claim to have ever used
the password store. My experience is limited to attempting to make
portions of auth-source-pass behave more like other back ends for the
purpose of improving its integration with ERC, the result being the
option `auth-source-pass-extra-query-keywords'. However, the patch seems
to make sense from a layman's perspective, for whatever that's worth.

Cheers,
J.P.
