Ah, right, the cache (gets me every time). BTW, it's probably still
worth mentioning the incompatibility in NEWS and the docs.

Wow, thanks, this is really helpful. Based on that, I'm pretty sure
what's going on. Basically, the new behavior is geared toward blindly
replicating that of the other back ends, warts and all. But that means
some handy pass-specific features, like subdomain matching, are notably
absent. I've attached a demo patch that better illustrates this.

My main question for you is: do you think we ought to change the default
for `auth-source-pass-extra-query-keywords' to nil? What about
additionally demoting it from an option to a public variable intended
solely for use by dependent libraries instead of end users?
