Colors should only be output if we're outputting to a TTY. Pipes or
redirections should not be colored (they'll only confuse those who don't
recognize the escape sequences). CMake also has color routines already,
but I don't know off-hand how accessible they are from CTest code (i.e.,
might be static functions).
