I thank Manuela Giolfo, Ahmad Hasnaoui, Amirouche Moktefi, Zia Movahed and Kees Versteegh for information, corrections and comments that relate directly to things discussed below. I should also thank Kais Dukes of the Arabic Language Computing group at Leeds University, who sent me some very useful information before going silent — I hope I didn’t make myself a nuisance to him. None of these people are responsible for any errors of fact or judgment below.
