SSH packet logs: don't rely on locale's isprint().

Browse Source 
I've just noticed that on OS X I get high-bit-set junk in the text
side of my hex/ASCII dumps. That's going to confuse all sorts of
things that will interpret them in the wrong character set (indeed, in
many cases there won't even be a _right_ character set). Coerce to
ordinary ASCII.
