You’re right, my patches they keep the window configuration for some
definition of "keep" :-).  However, a much more correct definition of
"keep" than the one we have now.

As it should be.  But if we give xref.el a special interface it ceases
to be :-)

It seems Eli’s OK with the current behaviour minus the C-u RET.

Then perhaps ’a’ can be xref-quit-and-goto-xref if you’re not opposed to
that.

You’re right. SPC should be bound to xref-show-xref though, if we are
honour the SLIME ancestry.

Meh... Maybe. I don’t know. I would prefer to always use XREF and
project-find-regexp (that I just learned about, thanks!), if only that
could be enhanced to the much much faster ‘git grep’ in Git projects.
Perhaps we could work on that as a separate modification.
