T works again

5.3.59 · August 6, 2026

 - Bugfix: T and V work again as shorthand for TELL and
   VISIBLE.  Two immortal commands had been added in a spot that
   quietly claimed those letters, so typing t got you Unknown
   Command -- which looks exactly like a typo, which is why it went
   unreported for days.  Our fault, and sorry.  (Noticed by Rickrat.)
