Thanks for the review fixes!

I applied the new error message, and updated a comment for the
option declaration.

However I kept diag_set instead of tnt_raise. Because I hope this
file will become more C gradually. This is why you can already see
some box_check_*() functions returning -1 instead of throwing an
error.
