No big deal, but if you add one char to a question, the edit history says it's adding 5.
Thought you should know.
I think the reason for the discrepancy in the characters is that carriage return and line feed are counted separately so two carriage returns = 4 chars, plus the char you thought you added = 5.
Carriage return + Line feed + Carriage return + Line feed + character
Let's take your most recent edit as an example here...
You're not counting the newlines added, which the diff (apparently) is, in the character count.
