Excellent!

Hmmm ... I guess I'm trying to follow the documented protocol
published in AVR061 too closely.  That doc does not list 0x11
(Resp_STK_FAILED) as a valid response from the STK500 for that
command, thus avrdude considered it a protocol error (according to the
doc).  For other commands, Resp_STK_FAILED is listed explicitly as a
valid response so I explicitly checked for it in those cases, but not
this one.  Sorry about that :-/

So ... good catch!  Please commit.  You just saved me from trying to
get a Windows install going on my laptop to try and figure out the
problem, now I can spend that time doing something fun :-)
