 *
 * Judy1 set operations.
 *
 * The name of this function, "Judy1Op", was carefully chosen from
 * a list of alternatives:
 *
 *   Judy1Op()  - It's hard to see that O is a letter and not a zero.
 *   Judy1Set() - Sounds like you are setting a bit.
 *   Judy1BS()  - BS for Bit Set functions.
 *   Judy1SO()  - SO for Set Operations
 *   Judy1AndIDontGiveADarn() - too long but goes with
 *   Judy1WhoseOnFirst() - now called Judy1First() and
 *   Judy1WhatsOnSecond() - now called Judy1Next()
 *
 * But Judy1SetOp() would conflict with Judy1Set() if we rename Judy1Set(), so
 * Judy1Op() it is.
