Right.

But implemenations have to deal with zero-width columns anyway; if you set:

   column-count: 999999999

or something, you will effectively have zero-width columns. 

Given that we clip columns, I think it's managable. 

Another alternative is to try find some minimal column width, as
suggested here:

However, I don't see any simple ways to improve such overconstrained
situations. Feel free to propose something, though.
