Merge branch 'pw/rebase-reflog-fixes'
Fix some bugs in the reflog messages when rebasing and changes the reflog messages of "rebase --apply" to match "rebase --merge" with the aim of making the reflog easier to parse. * pw/rebase-reflog-fixes: rebase: cleanup action handling rebase --abort: improve reflog message rebase --apply: make reflog messages match rebase --merge rebase --apply: respect GIT_REFLOG_ACTION rebase --merge: fix reflog message after skipping rebase --merge: fix reflog when continuing t3406: rework rebase reflog tests rebase --apply: remove duplicated code
