GNU Emacs 23.0.0 does not display an iso-8859-6 accordingly

[Peter Dyballa]

Hello!

I have a file that starts with:

        ;;; -*- coding: iso-8859-6; -*-

Later it contains some Arabic characters. In GNU Emacs 22.0.50 this  
is recognised and the mode-line starts with -6:, i.e. ISO 8859-6. GNU  
Emacs 23.0.0 shows -1:, as does GNU Emacs 21.3.50. Nevertheless GNU  
Emacs 23.0.0 can display in *Character List* buffer an (arabic- 
iso8859-6) list. The *Character Set List* lists the 'arabic- 
iso8859-6' encoding.
