Another way would be to implement programmer-specific options.
If main finds an option that it doesn't know, it just calls 
pgm->parse_option().

There is one issue here, either we insist in "-E" appearing after 
"-c" (change of behaviour) or we need to buffer the options until we 
know the programmer.

This would also allow us to easily implement other programmer-specific 
stuff (e.g. the STK500-stuff like "set voltage").

BTW: Programmers that don't have programmer-specific options, would 
not have to be changed. We could just add a default-functions in 
"pgm.c" that returns -1 (i.e. "can't parse this option").

I just tested the exitspecs on Linux and they are fine except for the 
case mentioned in my last post.
