> + With option "-S" [SWITCH], choose the right switch statement
> through a binary search, not a linear search.
> + With option "-S" [SWITCH], emit straightforward comparisons
> instead of switch statements with just one "case" label.
> + With options "-S -p -t" [SWITCH, POINTER, TYPE], don't emit
> spurious empty elements at the beginning of the wordlist array.
> + With option "-D" [DUP] and not option "-S" [SWITCH], if there
> is no more room for duplicate entries in the lookup array,
> don't call `assert (i != 0)'. Instead, make the array larger :-)
> + With option "-D" [DUP], if there are no duplicates, don't
