Merge branch 'js/rebase-reflog-action-fix'

"git rebase" reimplemented recently in C accidentally changed the way reflog entries are recorded (earlier "rebase -i" identified the entries it leaves with "rebase -i", but the new version always marks them with "rebase"). This has been corrected. * js/rebase-reflog-action-fix: rebase: fix GIT_REFLOG_ACTION regression
