There are ~80 instances of set_fake_editor/test_set_editor/set_cat_todo_editor in that file that are not in subshells. I've converted them in a preparatory patch (that was fun), removing about 20 that can now safely rely on EDITOR=: (hopefully that will ameliorate the performance hit of ~60 extra subshells a little) >> + FAKE_LINES="edit 4 1 reword 2 fixup 3" git rebase -i A E && >> + echo x>file3 && > > We usually leave no space after the `>`, but we _do_ leave a space > _before_ the `>`. > >> + git add file3 && >> + FAKE_COMMIT_MESSAGE=edited git rebase --continue && >> + # rev-list does not support -g --reverse >> + git rev-list --no-walk=unsorted HEAD@{5} HEAD@{4} HEAD@{3} HEAD@{2} \ >> + HEAD@{1} HEAD >expected && > > Wouldn't this be better as: > > git rev-parse HEAD@{5} HEAD@{4} HEAD@{3} HEAD@{2} HEAD@{1} HEAD \ > >expect && Good point >> + test_cmp expected commits > > We usually use the name `expect` instead of `expected` in the test > suite.
