This is good news.

But it appears it is still being used (also by Autoconf tarballs, for
exaple), so we should be more gentle and careful in deprecating and
removing it, of we decide to go down that road.

OTOH, I'm not aware of any real use of 'dist-tarZ', 'dist-zip' or
'dist-shar' these days, so we might start to deprecate (but nor
remove yes) them from the next 1.13.2 release.

I agree that ever deprecating or tossing gzip would be a bad idea.
