| 32 * A literal CSI is stored as CSI KS_EXTRA KE_CSI. | |
| 33 * These translations are also done on multi-byte characters! | |
| 34 * | |
| 35 * Escaping CSI bytes is done by the system-specific input functions, called | |

| 37 * Escaping K_SPECIAL is done by inchar(). | |
| 38 * Un-escaping is done by vgetc(). | |
