ChangeSet@stripped, 2006-08-11 13:19:44+05:00, bar@stripped +4 -0
  mysqld --collation-server=xxx --character-set-server=yyy
  didn't work as expected: collation_server was set not to xxx,
  but to the default collation of character set "yyy".
      
  With different argument order it worked as expected:
  mysqld --character-set-server=yyy --collation-server=yyy 
      
  Fix:
  initializate default_collation_name to 0
  when processing --character-set-server
  only if --collation-server has not been specified
  in command line.

    Don't clear default_collation_name when processing 
    --character-set-server if collation has already
    been specified using --collation-server
