How does one trigger the notice?

See revisions.png. I'm not sure exactly how to reproduce, but it may be comparing a blank line with 2 or more.

Nevertheless, the logic error in the code is plain: it assumes an array index is defined without warrant.

I've hit this many times before, never got around to patching it.

  1. Create a new post, leave the content blank (Insert a space if need be, makes no difference)
  2. Update the content with a sentence.
  3. Compare the Revisions.
