Yep, and it works as expected if you pipe stdio instead of typing it.

Yeah, I'm that's a limitation of cmd.exe, but I was surprised to find that
I could only get 79 characters typed into the console when I run this code:
? length( gets(0) & 0 ) - 1
I suspect that it's something to do with the console buffer not wanting to
do a line wrap, but I haven't dug deep enough to figure out if that's true.
I haven't tried at all with linux.
