Review Request 130210: initial doc update for 4.8.1

[Jack]

[to the list and not posted to the review]

I've published the final review, and I thought the next step would be  
to land it, but

"rbt land --dry-run" or "rbt land --dry-run 4.8" tells me
      "ERROR: Please specify a destination branch." and

"rbt land --dry-run --dest 4.8" or "rbt land --dry-run --dest 4.8" say
      "ERROR: The local branch cannot be merged onto itself. Try a  
different local branch or destination branch."

Is this because I made my changes in the 4.8 branch instead of a branch  
created specifically for this review?  Am I correct that now I need to  
do a "git push" and then "rbt close" separately?

It seems I'm just learning rbt/ReviewBoard right in time to switch to  
Arcanist/Phabricator.
