Some minor changes:

+ Detach TEXTAREA input field from simple input fields
  (concerning its setter) and remove WRAP? parameter from
  make-simple-default-setter
+ Rename TOLERATE-OLD-SELECT-OPTIONS to SIMPLE-OPTIONS
+ Deprecate MAKE-ANNOTATED-SELECT; it's not useful anymore
+ Merge MAKE-SELECT and REALLY-MAKE-SELECT to one function MAKE-SELECT
