How do I suggest a 1-character edit?

Question

Every once in a while I encounter an answer which claims to be Python. However, most Python code is specific to either Python 2 or Python 3.

Often the answer starts with

Python

Which should be fixed to either

Python 2

or

Python 3

However, this edit is only one character. I need six to make an edit. If there's more to be changed, I'll do it. But often there's nothing wrong with the rest of the answer.

What should I do when encountering such answers?

Answer 1

I thought I might as well turn my comment into an answer:

If you really can't find enough to improve to add more than the two bytes for the space and the version number, just leave a comment. The author of the post as well as high-rep users don't have this 6-character limitation, and someone will likely take care of it.

Answer 2

I read this tip on the StackOverflow meta recently but I can't find the post. You could add the comment to the post:

<!-- workaround for 6 character edit limit -->

and make the 1-2 character change. Then a higher rep user will see it in the review and can take the comment out with the improve the edit option.
