transaction-summary: show phase changes statistics in pull/unbundle
Upon pull or unbundle, we display a message with the number of
changesets which phase became public. Noticeably, this new message would
appear even if no new changeset were added (below the "no changes found"
message), thus indicating that something actually happened to the local
repository.
