I cannot imagine a situation where I would want to use the same window
(i.e., show the shell buffer in the window from which I called shell).

IIUC, your patch will use the current window in some circumstances,
and, since you want to use `display-buffer-reuseor-same-window' in
`shell'-like functions, I will not be able to avoid that.

I would much prefer that we use `pop-to-buffer' or `display-buffer'
everywhere (deprecating all those `pop-to-buffer-*' functions)
and let the _users_ decide how to display _all_ buffers using the standard
`display-buffer-alist' functionality.
