9term: add a "look" menu item (#299) Add a menu item which functions similar to acme's `Look` command. This is copied from 9front. See: https://code.9front.org/hg/plan9front/rev/1f1596dbca51 https://code.9front.org/hg/plan9front/rev/d2de1d2f7b48

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 the program behind the window isn't reading from /dev/cons, it won't take 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.

9term: set TERM=dumb instead of TERM=9term Everyone seems to assume that TERM != dumb implies ANSI escape codes are okay. In fact, many people assume that unconditionally, but it is easier to argue back about TERM=dumb than TERM=9term. This applies to acme win too, because they share the code. Set termprog=9term or termprog=win for clients who need to know. R=rsc CC=r https://codereview.appspot.com/12532043

9term, acme: autoscroll Ignore scroll/noscroll window setting. Instead, scroll when the write begins in or immediately after the displayed window content. In the new scrolling discipline, executing "Noscroll" is replaced by typing Page Up or using the mouse to scroll higher in the buffer, and executing "Scroll" is replaced by typing End or using the mouse to scroll to the bottom of the buffer.
