As designed, the middle section of the pipe 'colordiff --color=no' serves *no purpose whatsoever* and should be omitted but someone required it in some odd corner case.] I accept that the documentation and the code don't match and that your patch sounds sensible. I'll either accept entirely as-is or, possibly, slightly modified. Given the primary purpose of colordiff is to add colour, in the case of any ambiguity, it will add colour rather than not. I agree that if one explicitly says 'color=no' it shouldn't add colour; even though this remains in my eyes and entirely pointless & unnecessary use of colordiff!
