Thanks very much for the patch, Bernard. I have tested it and it is
now comitted.
Note that I did not see any improvement in programming time, however.
My simple test with a 20K program file using an AVRISP reporting
itself as firmware revision 2.1 takes 55 seconds to program. If I
recall, this is about 3 times as long as the Version 1 protocol.
It see a note from Erik Walthinsen who originally implemented the
STK500 V2 support saying the same thing:

So ... at least I'm not going crazy.
