[RFC/PATCH 0/3] pull: warning improvements part 2

This patch series goes on top of fc/pull-merge-rebase, however, I don't know how I should communicate that clearly, so I'm sending this as RFC to avoid any possible merging issues. It's not really an RFC, and in reality this is not v1, but the end result of many iterations, simply rebased on top of Junio's changes.

While updating the documentation (yet again) I noticed it didn't follow from one paragraph to the next (not a good story). So I decided to rewrite it adding a lot more detail.

The warning has also been changed completely taking into consideration the imput Jeff King shared with us in 2013 from GitHub trainers.

And finally one low-hanging fruit patch.

I have many more in the queue though.
