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.

doc: correct example concerning "hg purge" alias in man page "hgrc.5" The "hg purge" alias as currently described in "hgrc.5" only works, if the caller's current working directory is identical to the repository's root directory. This patch slightly modifies the example by adding an empty pattern as a file argument to the "hg status" command, thus forcing this command to list the affected files relative to the current directory.
