Re: [css3-flexbox] alignment test

The current version of the spec doesn't say what to do with margin: auto,
although previous versions said to treat it as flex(1).  We have been
treating margin: auto as margin: 0.

I think the reason Tab gave for removing the margin:auto behavior was that
it was redundant with what flex-align already provides.
