Ok, thanks.

(define-derived-mode xref--xref-buffer-mode fundamental-mode "XREF"
   "Mode for displaying cross refenences."
   (setq buffer-read-only t)
   (setq next-error-function #'xref--next-error-function)
   (setq next-error-last-buffer (current-buffer)))

This looks dubious to me. What if I already have a compilation buffer open, and I'm using `xref-find-definitions' to follow the implementation of some code near one of the errors?

This seems like it'll break the error chain I'm currently following.

Also, when I'm using xref-find-definitions (as opposed to the other xref-find- functions), I'm very unlikely to want to visit all results. It's usually just one that I'm after.
