Can we fix the character limit for edits?

In the question:

Why does this use, in Java, of regular expressions throw an "Unclosed character class" exception at runtime?

The OP has nothing that needs to be changed in regards to content. However, they didn't format any of their source. I want to just edit the source and call it done, but there is a 6-character limit.

Does the limit make sense in this case?
