[css-flexbox] Example 3 mentions "justify-self" when I think it wants to say "justify-content"

In section 4.1 of the Flexbox ED (the section on Absolutely-Positioned
Flex Children), there's a chunk labeled "Example 3" which says:

 # For example, by default, the static position of an
 # absolutely positioned element aligns it to the
 # main-start/cross-start corner, corresponding to the
 # default values of justify-self and align-self.
 # Setting justify-self:center, however, would center
 # it in the main axis.
http://dev.w3.org/csswg/css-flexbox/#abspos-items

This is the only mention of "justify-self" in the whole document, so I'm
guessing that's a mistake.  I think it means to say "justify-content"?
(justify-self is not defined in the flexbox spec, though it is defined
elsewhere, in the CSS Box Alignment spec.)

Also: it'd probably be worth explicitly saying which element to set this
property on, since (for justify-content) it applies to the container,
*not* the abspos child.  So e.g. "Setting justify-content:center _on the
flex container_ ..."
