 winrestview({dict})
 		Uses the |Dictionary| returned by |winsaveview()| to restore
 		the view of the current window.
+		Note: The {dict} does not have to contain all values, that are
+		returned by |winsaveview()|. If values are missing, those
+		settings won't be restored. So you can use: >
+		    :call winrestview({'curswant': 4})

+		This will only set the curswant value (the column the cursor
+		wants to move on vertical movements) of the cursor to column 5
+		(yes, that is 5), while all other settings will remain the
+		same. This is useful, if you set the cursor position manually.
+
 		If you have changed the values the result is unpredictable.
 		If the window size changed the result won't be the same.
