Merge branch 'jk/reflog-walk-maint'

After "git branch --move" of the currently checked out branch, the code to walk the reflog of HEAD via "log -g" and friends incorrectly stopped at the reflog entry that records the renaming of the branch. * jk/reflog-walk-maint: reflog-walk: include all fields when freeing complete_reflogs reflog-walk: don't free reflogs added to cache reflog-walk: duplicate strings in complete_reflogs list reflog-walk: skip over double-null oid due to HEAD rename
