[Joerg Wunsch]

Follow-up Comment #3, patch #7062 (project avrdude):

>> Curious, are you aware of patch #6502?

Well, you could have attached a file to the old patch I think.  But
it's OK that way as well.

I know, though for the purpose indicated in the patch (initial
programming of a bootloader), it's probably not too bad an idea
either.

I'm afraid that's the case, yes.

OK, I see.  Thanks for the clarification!
