FIXME: there is a problem when you call gnome_spell_check(spell, "bogus bogus"):
if you accept bogus the first time, it will be reported again
because ispell checked it before...
The easiest solution is to spell-check a word at a time (but it's slow).
spell :
Pointer to GNOME spell checker object.
str :
String to be spell-checked.
Returns :
1 if spelling is ok, 0 if not, -1 on system error.
