"git reset --no-mixed" behaved exactly like "git reset --mixed", which was nonsense. If there were only two kinds, e.g. "mixed" vs "separate", it might have made sense to make "git reset --no-mixed" behave identically to "git reset --separate" and vice-versa, but because we have many types of reset, let's just forbid "--no-mixed" and negated form of other types.
