I don't know if there is a binary patch out there in netland, but
the famous 'ECHO OFF' problem can be solved using an undocumented
feature of DOS 3.3: Lines beginning with the '@' (at) character
are never echoed. Replacing 'ECHO OFF' with '@ECHO OFF' will spare
your sore eyes the ungainly sight :-) of an echoed 'ECHO'.
