This question already has an answer here:
There are many questions which have bad SO/markdown syntax, most notably when referring to code. I like to fix this syntax and add the appropriate language tag so that the code is nicely formatted. However, often my edit is not big enough to be allowed, even though the net effect of the edit would in fact be a substantial improvement to the question.
Has there been any consideration to change the edit size requirements for such circumstances?
update see my feature proposal here: Proposal: inform <2k user who attempts <6 char edit that they need 2k to do it
