ncurses: Install 256 color terminfo files
PATCH 1/1 ncurses: Install 256 color terminfo files
There are three 256 color terminfo files that buildroot only installs if ncurses is configured with wide character support, which also enables ext-color. There is a fourth 256 color terminfo file and does not depend on wchar suport and is always installed.
This changes that to always install all four 256 color terminfo files.
When ncurses has ext-colors enabled,it allows 256 fg and bg colors at the same time. Without ext-colors, it is still possible to use the 256 color terminfo files and one can get a combination of fb and bg colors that equals up to 256, e.g. 256 fg colors on one background or 16 fg and 16 bg colors.
In short, the 256 color files work fine without wchar or ext-color support and support more colors than the normal xterm, etc. terminfo files. It's common today for the default terminal to use xterm-256color and it's nice if thinks like vim and top work out of the box.

The patch looks fine, but I'm confused when you say "all four 256 color terminfo files", while the patch only changes the installation of three terminfo files. Could you explain ?

The fourth file is already always installed. I change from 3 wchar dependent plus 1 unconditional to 4 unconditional.
