ncurses: 6.0 -> 6.0-20170729

[layus]

Ncurses has no stable release since v6.0 which was released two years ago.
Given that even debian started using unstable weekly updates, I see no issue in doing the same.

This has been tested on my package set, but not the whole nixpkgs.
⚠️ this is a small mass-rebuild.

Fixes #19785.

Does upstream want the world to use their unreleased version?

@bjornfor I would say that this is the versioning scheme of ncurses. Every distro is using these, from debian to fedora. I can however ask to the main developper, but I am not sure it is worth bothering him with that.

I noticed after the upgrade to 6.0-20170729, tig used in a zsh session with TERM=xterm-256color has display problems. No crash, just that the graph is visually off.

Downgrading ncurses back 6.0 or upgrading to 20170902 fixed the issue I experienced.

I will submit a pr.

@tsaeger Oh crap, I guess that is what I get for using unstable releases. I assume that you fix was http://invisible-island.net/ncurses/NEWS.html#t20170827.

I hope they will release an official release in the near future, but I thank you for your PR in the meantime.
