Assorted rust tools emit terminal codes to non-ttys

[mcandre]

Some rust tools, inclusing rustc and cargo, emit terminal codes when the terminal is not an interactive user session. For example, rustc may be run from within a vi or emacs terminal, or cargo may be piped to less.

In general, command line tools should disable terminal codes when !tty(), so that the output can be better processed.

This is attempted to be done today. Can you tell us exactly what case is going wrong for you?
