>Description:
Hello,

rxvt-unicode version 9.09 was released last month. It added support for 256 colors in the default configuration, and the default value of $TERM changed to rxvt-unicode-256color (from rxvt-unicode).

This results in slightly incorrect colors, and some programs like vi(1) refusing to work.

After a short discussion[1] with Chip Camden, it appears that rxvt-unicode-256color needs the same definition as rxvt-256color. The attached patch (against HEAD) installs this definition.

>How-To-Repeat:
Install rxvt-unicode version 9.09. Check that $TERM is rxvt-unicode-256color, and that the terminal can indeed display 256 colors.

Log into a FreeBSD system. If the shell is zsh(1), observe that backspace only outputs a space, and that ^U doesn't erase the line. Use vi(1) to edit a file, observe that it fails with « vi: No terminal database found ».
>Fix:
Apply the attached patch (again, against HEAD, not against 8.1-RELEASE) to usr/share/misc/termcap, and run cap_mkdb.
