  Log:
    lib/rdoc/markup/: Remove wrong call to `=~` against Array
    
    `@res` is an Array, so `@res =~ /\n\z/` calls `Object#=~` which always
    returns nil.
    I guess it should be `@res.last =~ /\n\z/`, but the change causes test
    failures.
    
    This bug was found during work for removal of `Object#=~`.
    [Feature #15231]
