Hello Florian,

thanks for your patch, I've commented on it inline.

No reason beside that nobody cared about it yet, I guess.

This makes a flaw in set_target_flash() obvious now. Not all programmers
have a socket. I just checked set_target_flash() silently fails with an
SF 100. So we should check for compatibility there or at the calling
site.

This reads confusing now (set 1, 2 or 3 to choose between 1 and 2?).
