Now ispell dictionary can eat dictionaries in MySpell format,

used by OpenOffice. Dictionaries are placed at
http://lingucomponent.openoffice.org/spell_dic.html
Dictionary automatically recognizes format of files.

Warning. MySpell's format has limitation with compound
word support: it's impossible to mark affix as
compound-only affix. So for norwegian, german etc
languages it's recommended to use original ispell format.
For that reason I don't want to remove my2ispell
scripts, it's has workaround at least for norwegian language.
