I recently came to edit a question, which required the adding of a couple of format tags as his original code couldn't be read, as the original code contained some SO-specific markup. But when I submitted the edit, it said that my edit must be 6 characters minimum. I feel that this limit is poor because the quantity of code and the clarity of the post can be massively affected by a pair of backticks in the right place or clicking the code button once- that is, the edit limit should take into account modified characters, even if those characters are indirectly modified by markup instead of changed directly.
Is the post so otherwise perfect that nothing else in it can be improved? Really? If so then it is a rarified post indeed..
