People who use the manual as a reference seldom read the entire node.
Instead, they read the description of the single subject they were
looking for, and move on.  If the reader was only interested in
reading about "M-.", with your version she will not see the
description of the XREF buffer, unless she reads on.

So I don't think the repetition here is a bad idea, especially since
it doesn't really repeat the same text.

When the original style is clear and unambiguous, I usually avoid
changing it, because style preferences are personal.

The additions for the new and changed bindings are, of course, okay,
that wasn't what prompted my comment.

Please show the final patch with the above comments fixed, and I think
it's okay to put this on emacs-26 after all.

Thanks.
