The following things have been renamed:
- file aspell.conf -> spell.conf
- options aspell.* -> spell.*
- bar item aspell_dict -> spell_dict
- bar item and local variable aspell_suggest -> spell_suggest
- info aspell_dict -> spell_dict
Some long lines in docs were causing a zoom, and then the text font was
smaller than it should be. Some styles have been fixed to remove the zoom
and keep the original ratio.
