- * Macros and things to deal with control characters.
- *
- * Unctrl() is just like the standard function, except we don't want
- * to include curses.
- * Isctrl() returns true for all characters less than space and
- * greater than or equal to delete.
- * Isprt() is tab and all characters not isctrl().  It's used
- * by wwwrite().
- * Isunctrl() includes all characters that should be expanded
- * using unctrl() by wwwrite() if ww_unctrl is set.
