It's awfully outdated.  Bidirectional editing in Emacs is no longer
"work in progress", since the release of Emacs 24.1.

There isn't any.  Why would you need one?

Does it help to type "C-x C-+"?

That is already so by default.

No need, Emacs determines the correct base direction of each paragraph
automatically, using the method described in the UAX#9.

And paragraph direction has very little to do with display of
bidirectional text per se.  The latter works no matter what is the
paragraph's base direction.  If it didn't, you'd be unable to have R2L
text in a middle of an otherwise L2R paragraph.

Likewise, not needed.
