recent xterm/terminal(?) change (control-C) shows ^C?

[Justin Piszcz <jpiszcz@lucidpixels.com>]

Hello,

Distribution: Debian Testing

Recently, after an apt-get dist-upgrade, when I hit control-c, I get the
following in an xterm:

$ ^C

It occurs with aterm/xterm, bash and csh.

Before, when I hit control-c, it would not show ^C on the console (makes 
it easier when copying/pasting items from the command line)

I never recall this occurring before-- does anyone which character 
mappings are responsible for this?

I wish to disable this behavior.

Justin.
