Hi guix!

I noticed the update to the password-store yesterday and so got curious
what changes we had and took a look at the git repository. I was really
happy to find the emacs package includes a fix [0] for a bug I've been
experiencing for a long time, where using pass inside EXWM would
deadlock emacs.

Taking a closer look as well, the commit also fixes a potentially quite
critical security issue with the package, I think we better apply it :-/.

Is this OK to commit? I've tested this locally on EXWM via ivy-pass.

Thanks,
Pierre

I figured this patch is just a straight-forward update, and quite an
important one, so I've just gone ahead and pushed it, adding an extra
comment that the emacs package version doesn't match the password-store
program version.

I figured maintainer's time are better spend not reviewing trivial
patches too much unless it's for onboarding newcomers :-).

Please shout if there are any issues!

Thanks,
Pierre
