The pg_rewind docs currently assert that the state of the target's data directory after rewind is equivalent to the source's data directory. This clarifies the documentation to describe that the base state is further back in time and that the target's data directory will include the current state from the source of any copied blocks since the point of divergence. This commit also improves the section "How It Works": - Describe the update of the pg_control file. - Reorganize the list of files and directories ignored during the rewind.
