Horrible BUG fixed (was Re: Windows Denemo Shutdown: SantaLuciaWoelkiDec13.zip)

[Richard Shann]

I've fixed a horrible bug which has been lurking in the code since 16th
May 2016 (that is since release 2.08). It should affect anything using
the deleting measures in all staffs command, but strangely has never
shown itself running under Unix and has just been reported as it
affects the "New from Current" command under Windows.
Thanks to Joe for reporting this - the fix is in now and should be
built tonight.
