Ah, thank you.  That was the clue that I needed.

For those also having this problem:

mintty.exe -o "KeyFunctions=c:break" -o CtrlExchangeShift=true -

will propagate Ctrl-C to the non-native apps and kill them, imitating the behavior of 3.0.X Cygwin.

Now that I have played with this for a while, I am thinking that I like the new behavior better and I have assigned a new key to specifically kill native Windows programs instead letting the Ctrl-C do all the work (I am using Alt-F5 to do this).
