This is not ok:  $ECHO may only take one argument, so you must
double-quote.  Furthermore, the argument may not start with a hyphen in
general, for it might be misinterpreted as option to the $ECHO command.
The solution is to use the slower
  $ECHO "X$what $ever" | $Xsed

I see this bug is in several places here.  :-/
