+ * Having never seen a terminfo system without curses, we assume this
+ * inclusion is safe. On systems with color terminfo, it should define
+ * the 8 COLOR_FOOs, and avoid us having to guess whether this particular
+ * terminfo uses BGR or RGB for its indexes.
+ *
+ * If we don't get the definitions, then guess. Original color terminfos
+ * used BGR for the original Sf (setf, Standard foreground) codes, but
+ * there was a near-total lack of user documentation, so some subsequent
+ * terminfos, such as early Linux ncurses and SCO UNIX, used RGB. Possibly
+ * as a result of the confusion, AF (setaf, ANSI Foreground) codes were
+ * introduced, but this caused yet more confusion. Later Linux ncurses
+ * have BGR Sf, RGB AF, and RGB COLOR_FOO, which appears to be the SVR4
+ * standard. We could switch the colors around when using Sf with ncurses,
+ * which would help things on later ncurses and hurt things on early ncurses.
+ * We'll try just preferring AF and hoping it always agrees with COLOR_FOO,
+ * and falling back to Sf if AF isn't defined.
+ *
+ * In any case, treat black specially so we don't try to display black
+ * characters on the assumed black background.
