To save others the trouble of figuring out just exactly what this erratum even *is*: in the original text, the numbers in the diagram rulers align above the minus signs. In the "corrected" text they align above the plus signs. I would like to remind anyone who might submit an erratum in the future: please use the "notes" section to make it clear what your proposed change is, unless it's perfectly obvious.

Looking at https://www.ietf.org/iesg/statement/errata-processing.html, we have 

> 	• Rejected - The erratum is in error, or proposes a change to the RFC that should be done by publishing a new RFC that replaces the current RFC. In the latter case, if the change is to be considered for future updates of the document, it should be proposed using channels other than the errata process, such as a WG mailing list. 
> 	• Hold for Document Update - The erratum is not a necessary update to the RFC. However, any future update of the document might consider this erratum, and determine whether it is correct and merits including in the update. 
> ...
> Guidelines for review are: 
> 
> 	5. Typographical errors which would not cause any confusions to implementation or deployments should be Hold for Document Update.

The erratum either is for a typographical error, in which case it should be Hold for Document Update, or it's in error, in which case it should be Rejected. The guidelines don't offer a "this is a matter of taste" option, which I think is what applies here, unless someone can cite an RFC Editor style guideline specifying that the rulers are supposed to have the numbers above the pluses?

Right now my inclination would be go with Reject, but if someone can cite evidence that the proposed fix is objectively more correct than the current text (or if the mood of the WG supports that option, for that matter) we could do Hold for Document Update instead.

--John

P.S.: FWIW my eyes prefer the as-published text to the proposed "correction".
