I have always found "update *to* your current branch" very strange
phrasing (the earlier one said "to HEAD", but it amounts to the same
thing). You do not push *to* your branch. You push your branch to
somewhere else (namely, remote). I would understand if it said "If your
push of your current branch triggers a non-ff error, ...", though.

I think the change in this patch comes from a realization that a blanket
"Here is all you need to know for any and all non-ff error cases" is not
very useful, and it feels like it is going backwards to squash the "non-ff
but not the current" into one category.
The user may have been using the matching default, gets the use-upstream
advice and realizes that she is trying to push branches other than what
she wanted to push, and may say "git push $there master" to push only that
branch out. Then she thinks she learned enough to squelch the message in
$HOME/.gitconfig.
She may have another project with remote.$there.push set to push more than
one branches out (say, master and next), and while on 'master', may hit
another "non-ff on other" instance, because her 'next' was stale.
She never gets a chance to see the other checkout-pull-push message, does
she?

The change in this patch is merely clarifying what pushNonFastForward
advise has already taught them ("Non-ff was rejected; the manual will tell
you what you wanted to do") by dividing them into three categories and
giving different advices to these categories. As the user says he
understood what he is doing, I think squelching all of them is a sane
choice.

In any case, the updated messages read much better than the current non-ff
one (or the previous round for that matter).
