Usage:: hg log --style phases Why do we need this new style - in what way is it different from or similar to existing styles? The new style is default + phases information. With the new phases feature the users exhibited their desire for a new style that could help them. Why do this need a new style - couldn't it be folded into an existing style? The default style and the new one are about the same, the difference is the phases tag. The users find both styles useful, this means that the both styles must exist.
