@Someone This particular edit was not "doing almost no change". It fixed a typo in the title. the initial title was: "Ubuntu is asking me password for small small things". Note that "small" appears twice. Also the correct syntax is "ask for something", which the edit also addresses. Improving the edit would be the best choice, as there are more issues that can be fixed (obviously I did the wrong selection), but also approving it would be OK IMO. I wouldn't reject it in no case.
