Subject: Prefix arg for xref-goto-xref
Date: Fri, 13 Nov 2020 10:18:51 +0200

I recall endless discussions about xref in the past.
But now I realized that xref-goto-xref just misses
an obvious thing, and nothing more is needed.

Like e.g. 'quit-window' allows using a prefix argument
to change its behavior by relying on (interactive "P"),
xref-goto-xref should do the same:

diff --git a/lisp/progmodes/xref.el b/lisp/progmodes/xref.el
