Correct, but it is a "you could instead do it this way" that is not
accompanied by a "you do not want to do what you said you want to
because.." answer. Having the latter is often helpful to learn why
the suggestion is actually not a mere "you could" but is a "you are
better off doing it this way".
Even though it is discouraged, people script using the Porcelain
"git diff" command, and once users of such a configuration variable
is used in Doron's fork of Git, those scripts will break for them.
Using alias like you showed won't have such a problem.
