Possible Duplicate:
How to overcome “Edits must be at least 6 characters”?

Recently I came across this answer on Stack Overflow

It has so many upvotes but it is not working because answerer got it wrong this line

NSKeyedArchiver  *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];

It should be corrected as

NSKeyedUnarchiver  *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];

So I tried to correct it by adding Un to answer body. But I got this message.

Oops! Your edit couldn't be submitted because:

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

Is it wrong to correct a answer like this?

    Even if it had more than 6 chars, that edit is likely to be rejected by the reviewers because it changes the code. (Not saying that's right, just what's likely to happen). There's a comment on the post that also says it should be "NsKeyedUnarchiver", best thing to do is upvote that comment. – S.L. Barth - Reinstate Monica Sep 7 '12 at 8:17
  • Find something else to edit. For example, there are several identifiers in text that aren't formatted as code. @S.L.Barth Even without knowing Objective-C, it's clear that the class names must match, and that this bit was copy-pasted and the author forgot to edit one piece. I know that reviewers often get it wrong, but it's no reason to discourage correct edits. – Gilles 'SO- stop being evil' Sep 7 '12 at 10:34
