bug#36877: 25.3; uniquify renaway uniquify-managed list

[David Biesack <David.Biesack@Apiture.com>]

Note that this problem is still persisting for me, both in Emacs 26 and also in Emacs 27.1
which I just upgraded to.

I have implemented a workaround to the uniquify-managed list growing
Exponentially after using revert-buffer. See this patch

    No, uniquify-after-kill-buffer-p is set to t in my session; no customization.

        The attachment seems to be missing.  But anyway, I have a simple
        reproducer now, so we don't need any more backtraces.  I found setting
        uniquify-after-kill-buffer-p to nil was needed to reproduce this, do you
        have that setting in your init?
