 #  #
   #    Modify institutional sections (using customized &instsec_reformat()
   #    routine in localenroll.pm), to either clutter or declutter, for  
   #    purposes of ensuring an institutional course section (string) can
   #    be unambiguously separated into institutional course and section.
   #
   # Formal Parameters:
   #    $cmd     - The command request that got us dispatched.
   #    $tail    - The tail of the command.   In this case this is a colon separated
   #               set of values that will be split into:
   #               $cdom        - The LON-CAPA domain of the course.
   #               $action      - Either: clutter or declutter
   #                              clutter adds character(s) to eliminate ambiguity
   #                              declutter removes the added characters (e.g., for
   #                              display of the institutional course section string.
   #               $info        - A frozen hash in which keys are: 
   #                              LON-CAPA course number:Institutional course code
   #                              and values are a reference to an array of the
   #                              items to modify -- either institutional sections,
   #                              or institutional course sections (for crosslistings).
