tweaks: add a consistency check plus a corresponding warning

Since commit 4c6ec637 from about half a year ago, the 'action' parameter
of update_undo() is unused.  Verify that this parameter matches the type
of the item at the top of the undo stack, so that in another half year
the parameter can be safely removed.
