+ * - recorded chracters: for the "q" command.
+ *
+ * The bytes are stored like in the typeahead buffer:
+ * - K_SPECIAL introduces a special key (two more bytes follow).  A literal
+ *   K_SPECIAL is stored as K_SPECIAL KS_SPECIAL KE_FILLER.
+ * - CSI introduces a GUI termcap code (also when gui.in_use is FALSE,
+ *   otherwise switching the GUI on would make mappings invalid).
+ *   A literal CSI is stored as CSI KS_EXTRA KE_CSI.
+ * These translations are also done on multi-byte characters!
+ *
+ * Escaping CSI bytes is done by the system-specific input functions, called
+ * by ui_inchar().
+ * Escaping K_SPECIAL is done by inchar().
+ * Un-escaping is done by vgetc().
