Rev 24: a REFLECTION against a permanent curse afflicts both wizards

"If this spell is REFLECTed, both players take 1/2 point of damage per
space moved" (WALKING DEAD); "In case of REFLECTION, both players are
affected" (IDIOT); SLOW DEATH follows REFLECTION's own rule that a
spell works for both parties. A permanent curse has no duration for
the reflection's split to halve, so the caster went untouched; the
curse is now laid on them as well, as if cast back. Older games replay
as they were; PRPM, reflected at seq 108 with no move since, was
re-stamped to 24 at its table's request.
