VB indentation incorrect when 'Next' is used as IdentifierOrKeyword

The following code is indented incorrect when pressing Ctrl+I:

Public Class NewClass
    Sub Test(rnd As Random)
        rnd.Next()
    End Sub
End Class

The indentation logic incorrectly assumes that 'Next' indicates a block
end. Escaping the keyword "rnd.Next" works around the issue.
The indentation logic should ignore keywords if they occur after a dot
(IdentifierOrKeyword production in the grammar)
