+    In 4.x we used the event's len to compute the positions here. This is
+    wrong if the event was 3.23/4.0 and has been converted to 5.0, because

+    will make a wrong group_master_log_pos (yes it's a bug in 3.23->4.0
+    replication: Exec_master_log_pos is wrong). Only way to solve this is to
+    have the original offset of the end of the event the relay log. This is
+    what we do in 5.0: log_pos has become "end_log_pos" (because the real use
+    of log_pos in 4.0 was to compute the end_log_pos; so better to store
+    end_log_pos instead of begin_log_pos.
+    If we had not done this fix here, the problem would also have appeared
+    when the slave and master are 5.0 but with different event length (for
+    example the slave is more recent than the master and features the event
+    UID). It would give false MASTER_POS_WAIT, false Exec_master_log_pos in
+    SHOW SLAVE STATUS, and so the user would do some CHANGE MASTER using this
+    value which would lead to badly broken replication.
+    Even the relay_log_pos will be corrupted in this case, because the len is
+    the relay log is not "val".
+    With the end_log_pos solution, we avoid computations involving lengthes.
