Hi-Tech doesn't do any strange translations; a 0 is a 0.

The only thing approaching an "idle" state with a PIC is the sleep
instruction.

Also note that you had the watchdog timer enabled, which will cause
the PIC to periodically reset.  This, along with the powerup timer,
means PORTB will return to hi-z state for ~72 ms after a reset.
