How to overcome “Edits must be at least 6 characters”?
Change this behavior to allow for spelling corrections and the like: “Edits must be at least 6 characters”

Sometimes I'd like to fix the indentation of a code sample in a question, but on submitting I get this error message:

Edits must be at least 6 non-space characters; is there something else to improve in this post?

Is there a way to work around this restriction without altering the content of the question?
