  *   0:  Don't handle keystring, just print-like escapes.

  *   2:  Handle ^X as well as emacs-like keys; don't handle \c
- *       for no newlines.
- *   3:  As 1, but don't handle \c.

  *   4:  Do $'...' quoting.  Overwrites the existing string instead of
  *       zhalloc'ing. If \uNNNN ever generates multi-byte chars longer
  *       than 6 bytes, will need to adjust this to re-allocate memory.
- *   5:  As 2, but \- is special.  Expects misc to be defined.

+ *   5:  As 2, but \- is special. If \- is seen, *misc is set to 1.
