I took your proposal to be specifically about what happens if the editor
is exited with no change to the buffer, and in that case, I would suggest
making no change to the buffer, but not re-executing it.

If the editor is exited after deliberately emptying the editor buffer,
I would expect that to be treated as emptying the query buffer.

I don't foresee any case that would entail bringing a /previous/ query
back into the query buffer.
