Edits must be at least 6 characters
Though I understand the reason for that and read discussions like this, it's even more annoying for questions with wrong or missing formatting. Questions with some file or commands given become completely unreadable without formatting.
If the first one reading the post could spend 10 seconds to correct the formatting, a bunch of other reader would save a minute figuring out the meaning. Unfortunally the edit usually consists of newlines and spaces only, but they don't count for the 6-char limit.
I don't want suggestors and reviewers to waste time with useless changes that are only made to avoid the limit. Can't whitespaces be couted for the limit? I believe abuse of that possibility is unlikely.
