How to get rid of all save() flash memory code?

Hi Gordon,
it looks like there is a little bug with the setSleepIndicator(LED1) which is not cleard with reset():
I set the Indicator and run a save(); but after a reset() and a following save(), the dump() still showed the setSleepIndicator(B2).
After calling setSleepIndicator() with undefined argument the dump is empty. So looks like this resists the reset() processing:

>dump()
setSleepIndicator(B2);
digitalWrite(B2,1);
=undefined
>reset();
=undefined
