`find-file' does not call `display-buffer'; `find-file-other-window'
does call `display-buffer'. (I just checked by enabling Edebug in

`find-file' calls `switch-to-buffer' which calls `pop-to-buffer'.

The same is true for all the other "put a buffer in this window"
user level functions I've encountered.

`display-buffer-same-window' is an action for `display-buffer'.

Ah! We could change the implementation of `find-file' to use
`display-buffer' with an action of `display-buffer-same-window'; that
action would be changed by prefix C-x 4 or C-x 5.

`find-file-other-window' could then be implemented by setting
`display-buffer-overriding-action' and calling `find-file'.
That would make sense, and should be mostly transparent to users. All
the other similar functions would have to be changed in a similar way -
I haven't tried to enumerate them. We could implement C-x 4 and 5 for
the current uses of `display-buffer' first, and see how people like it.
