Sorry, my formulation was probably unclear.  In Emas 23 you can often
resize the active minibuffer window manually (via `enlarge-window' or
`adjust-window-trailing-edge') regardless of the setting of
`resize-mini-windows'.  So should we keep that behavior or allow manual
resizing only when `resize-mini-windows' is nil?

The passive mini-window IIUC.

That's another issue.

Please try the new patch I attached.  It should mimic the behavior of
Emacs 23 as close as possible.
