* lisp/progmodes/xref.el (xref--xref-buffer-mode-map): Cease
binding 'g' to 'xref-revert-buffer'.
(xref--xref-buffer-mode): Set 'revert-buffer-function' to...
(xref--revert-buffer): ...this.  New function, renamed from...
(xref-revert-buffer): ...this.  Make it an alias of
'revert-buffer'.
* etc/NEWS: Announce it.
* doc/emacs/maintaining.texi (Xref Commands): Update docs.
