How to overcome “Edits must be at least 6 characters”?
I noticed a typo in URL posted in an answer. I know the correct URL, so I decided to correct it. I got this:
Oops! Your edit couldn't be submitted because:
Edits must be at least 6 characters; is there something else to improve in this post?
There is nothing more to improve in that answer. There was only single letter to be fixed.
Is there a good reason for this limitation or is it a bug? In my opinion, fixing a typo is a common event and is very valuable (especially in a URL).
