Bug#961932: nethack-lisp: broken and unmaintained

[Markus Koschany]

Package: nethack-lisp
Version: 3.6.6-1
Severity: serious

I have just updated nethack to the latest upstream version to fix
several security vulnerabilities and a compilation error with GCC 10.
Unfortunately the Debian specific lisp patches don't work anymore with
the current release. I could fix a few minor errors but there are more
issues and I'm not really interested in maintaining a fork of nethack.
Though I guess someone else can fix it. I have pushed all lisp related
patches to a new lisp branch in Git.

I wonder if we should drop nethack-lisp completely or try to upstream
the code. It is quite obvious that the additional work to make the
lisp port work prevents more regular updates.
