CTRL-C cancels the current line, similar to how getty works. This is useful if one is using a dumb terminal to communicate with a node, as it saves having to repeatedly type backspace to discard the current line. It also helps when connecting to an already running node, as one does not know what is on the line buffer, the safest thing to do is to begin by sending a ctrl-C. This is a suggestion of @benemorius.
