  Fix small glitch during parsing of ALTER EVENT xyz
  with only COMMENT clause. Strangely it has manifestated itself
  only on two platforms. This is a fix for bug#23423 
  "Syntax error for "ALTER EVENT ... COMMENT ..." on just two platforms"

    if COMMENT is used mark it as used.
    There was a missing setting to 1 of $$. If COMMENT
    was used in combinations with other clauses then it
    was passing.
