bug#27526: 25.1; Nonconformance to Unicode bidirectionality algorithm due to paragraph separator

[Itai Berli]

Thanks. I've never built Emacs from source. I think it might be easier for me to wait till this patch makes it to the official release.

It turned out to be relatively easy, so I implemented this on the
master branch of the Emacs Git repository.  There are two new
variables that you should set to "^" to get the behavior you wanted.
I hope you can build the master branch and see whether the new
facilities solve your case.

Thanks.
