Merge branch 'ag/edit-todo-drop-check'
Allow the rebase.missingCommitsCheck configuration to kick in when "rebase --edit-todo" and "rebase --continue" restarts the procedure. * ag/edit-todo-drop-check: rebase-interactive: warn if commit is dropped with `rebase --edit-todo' sequencer: move check_todo_list_from_file() to rebase-interactive.c
