This is now possible using the `window-height' and `window-width' alist
entries.  There are currently two major problems with this:

(1) `temp-buffer-resize-mode' overrides it.  This is no problem for
`with-output-to-temp-buffer' since that macro encapsulates the
`display-buffer' call.  But `with-temp-buffer-window' has an ACTION
argument which can be now overridden and manually activating
`temp-buffer-resize-mode' in a buffer will accomplish the same.

(2) I'm not sure what to do with `fit-window-to-buffer' and
`shrink-window-if-larger-than-buffer' calls that happen after
`display-buffer' like in `vc-root-diff'.  In principle, I could have
`display-buffer' add a window parameter or a buffer-local variable to
handle such cases.  But neither of them look very attractive to me.

Any suggestions?

I disagree here.  We should try to preserve the previous behavior.
