In this very case, if the Set lines are the only ones with a colon,
then this is suddenly a very easy two step task:
First replace ^[^:]*$ with nothing, then replace ^$ with nothing.
Done. But I guess that is not always the case, I'm not sure if that
was mentioned earlier in this thread. If so, sorry for bothering
again.
Maybe someone already suggested this, and I totally missed it as usual.
