Our existing "Refresh" action piggy-backed on the reload code, using a semantically-dubious empty list to indicate a lack of changes. One upshot of this was that undo-related functionality like modified flags were unintentionally cleared on refresh. This patch breaks out minimal required refresh functionality into a new method, and replaces the old set-empty-files idiom with a call to this method.
