I just pushed an improvement for Bidi. I did not do so earlier because I was trying to improve it further, but somehow I'm hitting a brick wall here. Could you please check, and tell me if what I already did is okay? In this case I did not find a good test case in the wild (or more precisely, I had no idea how to find one), so I concoted one myself. You'll find it here: https://www.heytings.org/data/locales.json . Emacs is still a bit sluggish with that file, but behaves much better than before. > > If you for some reason prefer to keep that branch active, can you please > merge the current master to it, so that the changes in narrow-to-region > will be on the branch? > Is that feasible? Non fast forwards are not allowed in the Emacs repository, so rebasing a feature branch is not possible (without using the workaround of deleting and recreating the branch).
