I've been using this for a while, and it works nicely.  But now
consiter this:

  set -x
  some command
  RC=$?
  { set +x; } 2>/dev/null
  test ! x$RC = x0 && exit $RC

I want only "some command" traced, not "RC=$?".  Yet I have to do
it before the "set +x" because the latter overwrites $?.  Any
ideas how to get around this?
