- * These buffers are used for storing:

- * - redo characters: will redo the last change.
- * - 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().
