[MathML3-last-call] bad example using mscarries

The first example using carries in 3.6.8.1 (Addition and Subtraction) is wrong.

<mstack>
  <mscarries crossout='updiagonalstrike'>
    <mn>2</mn> <mn>12</mn> <none/>

  </mscarries>
  <mn>2,327</mn>
  <msrow> <mo>-</mo> <mn> 1,156</mn> </msrow>
  <msline/>
  <mn>1,171</mn>
</mstack>

The crossout would apply to the digit below the <none/> which is not intended.  This can be fixed by adding a mscarry around <none/> as in:

<mstack>
  <mscarries crossout='updiagonalstrike'>
    <mn>2</mn> <mn>12</mn> <mscarry crossout='none'> <none/> </mscarry>

  </mscarries>
  <mn>2,327</mn>
  <msrow> <mo>-</mo> <mn> 1,156</mn> </msrow>
  <msline/>
  <mn>1,171</mn>
</mstack>
