Seems like this "counts your chickens before they are hatched" since it assumes your pull request will be approved. If I was you I would be tempted to write a brief comment that more literally explains the current status of this rather than assuming the change to the spec will go through.

Does this really reject tabs, line feeds, carriage returns, and sequences that form a segment break? The comment above lists all those special cases, and the code here doesn’t cover them. It seems like the comment might need to explain why the code below doesn’t match it?

Those are handled in the stanza right above this one.
