+	* src/browser.c (browser_refresh): Limit the selected file to the
+	available ones in the list -- after a refresh the number may have
+	decreased.  This fixes Savannah bug #45424.

 	* src/text.c (do_undo, add_undo): Skip undoing a backspace *only* when
 	it really tried to delete the final, magic newline.
