   FUNCTION:  strtrim   **MODIFIED** 88-01-09 by EF

      Given a string s1 (not neccesarily NUL terminated) it copies s1 into
      s2 less any trailing blanks

      modification: s2 will be NUL terminated
      modification: the order of the arguments has been changed
            to be consistent with the other str functions

   PARAMETERS:
   
      s1 = pointer to character array (string) (source)

      s2 = pointer to character array where s1 will be copied to 
           without trailing blanks    (destination)
        
      n = max number of chars to copy, including the NUL

   RETURNS:  VOID

       A case-insensitive string comparison function.
