Comment on CCS3 module: Multi-column layout

The example in section 6.1 of http://www.w3.org/TR/css3-multicol/ appears to
have an error.

DIV { width: 400px; column-count: 4; column-width: 100px; column-gap: 10px
column-rule: none; } 

Based on the explanation below the example the width of the DIV should
instead be

width: 300px

300px >= n * 100px + (n-1) * 0px + (n-1) * 10px * 2
where n is the largest possible integer 

The extra " * 2" at the end of the above equation also appears to be an
error.
