+	* src/winio.c (get_mouseinput): Properly find also the zeroeth
+	item from a certain menu in the list of functions.  Until now
+	this accidentally worked, because "Get Help" was the very first
+	item in almost all menus.  Partly fixes Savannah bug #42093.

 	* src/nano.c (precalc_multicolorinfo): Actually set the intended
