What about the others, though?  I wouldn't even expect *XREF* to be
eligible, as that is a kind-of "service" buffer to which I don't
really switch, I let the relevant commands put me there when needed.

Likewise for Eshell and Occur -- why are those candidates?  Basically,
any buffer whose name is *SOMETHING* should be by default excluded, I
think those that should be included are the exceptions, not the rule.

More generally, I question the wisdom of judging by the
default-directory in the first place.  Can't we come up with a better,
more specific criterion?
