My vote would be on not introducing additional properties for columns 
breaks, from an implementation/performance perspective. From a html/css 
author point of view, I would prefer to not mix up column and pages as 
it makes it unclear how to use the property. How about mixing it up in 
the values instead, so instead of having
    "page-break-<whatever>:<value>" and
    "column-break-<whatever>:<value>"
we would have
    "break-<whatever>:<page-value>|<column-value>".
For example: "break-inside: page", "break-inside:column", 
"break-inside:any", "break-inside:none", etc. 

I think this would be less ambiguous to the user as well as allow for an 
efficient implementation. This is roughly what is already proposed, with 
the difference that the wording "page-" be removed from the property 
name and used in the property values instead. Haven't really considered 
how these properties are used though.
