The cleanup has been done.  The final message of that subthread says:

  Anyone interested in renaming 'window--display-buffer' - please go
  ahead.  I think a 'display-buffer-' prefix should then be appropriate.

What I meant there is that calling it say 'display-buffer-in-window'
would be appropriate but the final name is up to its clients.
