update: change default destination to tipmost descendant (issue4673) (BC) Bare 'hg update' now brings you to the tipmost descendant (on the same branch). Leaving the user on the same topological branch. The previous behavior, updating to the tipmost changeset on the same branch could lead to jump from a topological branch to another. This was confusing and impractical. As the only conceivable reason for the old behavior have been address by the recently introduce message about other heads, we can "safely" change this behavior All test changes have been reviewed and seen a valid consequences.
