Sorry, I'm not sure I understand the question.  If you are asking how
to word the question we ask the user, here's my proposal:

  Keep the existing execution log? (yes or no)

I think the default should be NO, so that this does TRT when invoked
non-interactively.  If you agree, you need to use `nquery' for this
question.
