- 1 if the switch is true in a conditional spec,
- -1 if false (overridden by a later switch)
- -2 if this switch should be ignored (used in %<S)

+ SWITCH_FALSE to indicate this switch is overridden by a later switch.
+ SWITCH_IGNORE to indicate this switch should be ignored (used in %<S).
The `validated' field is nonzero if any spec has looked at this switch;
