OK.  I'm not interested in repeating an old discussion.  But it does 
seem that the release of 1.7 is a good time to decide whether the cygwin 
console is emulating linux or xterm or something else and then make this 
happen as much as possible.

FWIW, I just tried Andy's echokeys program in xterm and in mintty.  In 
xterm the output is \x81 with all four combinations of left/right.  In 
mintty, the output is ^[^A with three of the four combinations, and 
nothing in the fourth.  The one that generates nothing is 
left-ctrl/right-alt (corresponding to AltGr).
