			The code that reads the reflog from the newer to the older entries did not handle an entry that crosses a boundary of block it uses to read them correctly. * jk/for-each-reflog-ent-reverse: for_each_reflog_ent_reverse: turn leftover check into assertion for_each_reflog_ent_reverse: fix newlines on block boundaries
