cmd/9term: A hack because I'm constantly getting confused about ^C vs fn+delete
Since Google (and a lot of the outside) is so engrained with using
^C as interrupt, I'd like to be able to use it in 9term if I've
stty'd my intr to ^C. Without this, hitting ^C still works but if
tthe program behind the window isn't reading from /dev/cons, it won't
ttake effect till after I hit a newline which is often very confusing.
I know this is a hack since it only works if I stty intr ^C but that
seems the only other character that gets used anyways.
