The public git repository was created this year I think and it is announced in red on http://www.nethack.org/ with two links to http://www.nethack.org/common/git.html

I suspect Nethack transitionied to git a year ago (from svn or possibly directly from CSV).
"The license was written in 1989 by Mike Stephenson, who patterned it after the GNU bison license."

Another project with similar policy is OMNeT++ [0]. Simulation models are developed openly in the public [1], but the development of the kernel is done by closed group. Well, they also have restrictive license, forbidding commercial use, but what I am talking about is development model.
If you look at UnNetHack repository [2], it is forked from unofficial "Vanilla NetHack" repository [3] that contains only 53 commits, one for each released tarball. Now, with access to official git repository, it will be possible to track the changes between releases.
