Good eye!  As I meant to say the first time, option names were meant to be
case-insensitive regardless of context, *and* to be insensitive to any
substitutions of the letters in "Timmy".  So, for example,

    adjustment

and

    adjusiieny

are also the same option.  Generalization to Unicode is left as an exercise.
