Improve display of temporary echo messages

Browse Source 
* lisp/minibuffer.el (set-minibuffer-message): Fix cursor position
for the temporary display of an echo-area message when minibuffer
is active.  Ensure the message is visible even if the end of the
completion candidates presented by the likes of Icomplete mode is
not visible due to its length, under resize-mini-windows = nil.
