Returns whether the character at iter is within an editable region
of text. Non-editable text is "locked" and can't be changed by the
user via GtkTextView. This function is simply a convenience
wrapper around gtk_text_iter_get_attributes(). If no tags applied
to this text affect editability, default_setting will be returned.
You don't want to use this function to decide whether text can be
inserted at iter, because for insertion you don't want to know
whether the char at iter is inside an editable range, you want to
know whether a new character inserted at iter would be inside an
editable range. Use gtk_text_iter_can_insert() to handle this
case.
