+// This terminal definition is derived from the xterm-256color definition, but
+// makes use of the RGB property these terminals have to support direct color.
+// The terminfo entry for this uses a new format for the color handling introduced
+// by ncurses 6.1 (and used by nobody else), so this override ensures we get
+// good handling even in the face of this.
