Shift+Fn broken (mc) about mintty HOT 2 CLOSED

Mintty version is 0.9.1-1 from cygwin.

Thanks for looking into this, but you'll find that that's the same keycode as 
in xterm, which of course is what mintty tries to be compatible with. Shift+F6 
doesn't work in mc running in Cygwin xterm either.

Xterm, Konsole and gnome-terminal on my openSUSE install also send the same 
code, yet there Shift+F6 does work. The terminfo entry for Shift+F6 is 'kf18' 
apparently, and that's the same on both systems, i.e. 'tput kf18 | cat -v' with 
TERM=xterm prints '^[[17;2~' on both.

In other words, this looks like an issue specific to the Cygwin version of mc, 
similar to the problem with Shift+arrow at
