If you were running the world, you'd still need to add stg like

   YES, I DO MEAN IT, RTFM BEFORE ANYTHING ELSE, AND DON'T COMPLAIN
   BEFORE YOU REACH THE END OF THE MANPAGE.

or so, at least if your friends look like my students ;-)

It's not that far from what the manpage says indeed (it talks about
--force instead of +<refspec>, and mentions both pull and pull
--rebase). But when the user reached the point where (s)he's wiling to
read the doc and finds it interesting, then (s)he'll also read about
advice.pushNonFastForward and get rid of the whole (now useless)
message ;-).
