    lisp/org-colview.el: Add defcustom `org-columns-checkbox-allowed-values'
    
    * lisp/org-colview.el Add defcustom
    `org-columns-checkbox-allowed-values'.
    (org-columns-next-allowed-value): Introduce variable
    `org-columns-checkbox-allowed-values'.
    
    This would allow to use more than two states ("[ ]", "[X]") in columns
    with SUMMARY-TYPE that use checkbox ("X", "X/", "X%").  For example
    you can add an intermediate state ("[-]").  Or empty state ("") to
    remove checkbox.
    
    * etc/ORG-NEWS: New option ~org-columns-checkbox-states~.
