Edits under 6 characters should be allowed if in a hyperlink URL
Can't create a mark-down link when editing an existing answer
This answers link doesn't work (404); a commenter posted the right link. Everyone will still clicks the link in the answer, sees that it doesn't work, comes back, reads the comment, goes to the right link. Bad experience.
I tried to edit it, but I must at least change X chars. The fixed link only needs a few characters changed to work.
My assumption: broken links, especially where another use already has made the work to figure out the right link, must not exist. Is my assumption wrong?
