I'm fine using auto, it's what's currently implemented in IE10, however, rereading what fantasai originally wrote I'm not sure I'm getting the distinction between fit-content and minmax(min-content, max-content).

The minmax(p, q) function means max(p, min(fill-available, q)) doesn't it?  In this case the grid is determining what's available to the track i.e. supplying the fill-available argument to the function.

So what I'm saying is... I think auto works fine, but I'd like us to agree that the reason we're opting to use it instead of fit-content is because auto is shorter to type and not because we believe minmax(min-content, max-content) means something different that max(min-content, min(fill-available, max-content)).

In my mind all these expressions are saying the same thing:

1. Always be at least as big as min
2. Try to grow up to max
3. But stop growing if you run out of space before you get there
