Make gash commit the changes when all files are removed

This should be fixed properly in gash. AFAIK, we dont understand how the changed? == !@sha1, or the implications in gash for altering how the @sha1 is used to determine changed. This fix is to avoid touching @sha1. Its not meant to be the optimum / elegant solution.
