While editing this question to include a better title, I noticed that the body of the text had a stray lowercase i, and went to change it.
The error came back that my edit was too short (less than 6 characters). I was momentarily confused, because the title was all-new and plenty long, and then figured out it meant in the body. Could/should we either count title changes toward the minimum character change count or just mention that the error refers to the body of the question?
