[This is a bug report from an old issue discussed in
help-gnu-emacs@gnu.org (dated 19 Dec 2022, Message-ID
<7ac4ca06-cbbb-1c8d-0f59-2ccd5d3232f2@iki.fi>).  Dmitry Gutov asked me
to file a bug, which I unfortunately forgot to do that time.  Hence
filing now.]

I discovered a somewhat peculiar case where xref-find-references returns
duplicate references for elisp symbols.

Recipe:

1. Create a file ~/foo/bar/bar.el with contents:

  (defun bar-f ())

  (defun bar-g ()
    (bar-f))

  (provide 'bar)

2. Create a git repo in ~/foo/bar and commit bar.el.  This is just to
set up a project that Emacs can recognize.

3. Start emacs -Q and eval

  (add-to-list 'load-path "~/foo")
  (add-to-list 'load-path "~/foo/bar")
  (require 'bar)

4. C-x C-f ~/foo/bar/bar.el

5. M-x xref-find-references RET bar-f RET

On my machine I get

  bar.el
  1: (defun bar-f ())
  4:   (bar-f))
  1: (defun bar-f ())
  4:   (bar-f))

i.e. references are duplicated.  The issue seems to be in load-path: if
I remove (add-to-list 'load-path "~/foo") from step (3) above, then I
don't see any duplicates.
