Good.  Then I'm happy.

As for when we can't pop up a new window: would it be okay to reuse
the current window only in that (hopefully, rare) case?

How about 'Q'?

What behavior should become the default?

The problem with binding this "quit and go to reference" function to
RET is that it is unlike any other similar feature we have: RET
usually selects the item, but does not quit any windows.

I'd need to see the patches in their last incarnation (if you already
posted them, and nothing needs to be changed, a URL will be
appreciated).  In general, this changes user-visible behavior in
non-trivial ways, so it's borderline between a bugfix and a new
feature.  But if the patches are small and simple enough, I guess they
could be okay for emacs-26.

Thanks.
