   //    and AudacityApp::MRUOpen(), but if you open an aup file by double-clicking it
   //    from, e.g., Win Explorer, it would bypass those, get to here with no check,
   //    then open a NEW project from the same data with no warning.
   //    This was reported in http://bugzilla.audacityteam.org/show_bug.cgi?id=137#c17,
   //    but is not really part of that bug. Anyway, prevent it!
