Tangentially related: is there any reason now for showing the distinction
between [z3|z5|z8|...] files in the filename, when most people won't care,
and if you do it's trivial to make the distinction? Was there ever?

Maybe we could do a blanket extension change:
  .z3 }
  .z5 } -> .z-g
  .z8 }

  .sav  -> .z-s
