Nit: Capitalize the first letter and end the sentence with a period.

Julien is right that this style is rare.  I see it mostly when setting min and max preferred width to the same value.  I don't think it's actually against the style guide and this seems fine to me.

Yup. As to whether it's more readable, it just seems like a matter of taste. I find this more clear for these functions that all have the same pattern of setting the min and max widths.

The readability argument stems from not being consistent with the rest of the code (which is not something subjective). It's easy to browse over this code and miss that both logical widths are set up.

Also it *is* a style violation, I just couldn't find the relevant point in the coding style: see http://www.webkit.org/coding/coding-style.html, Line breaking, point 1. "Each statement should get its own line."

It *is* consistent with all the computePreferredLogicalWidth functions that do this. I feel like this pattern makes it much easier to browse this code and see that they're just being set to the same value.

I think this case is not what this style rule is referring to, but I see how it's open to interpretation. If you want an official ruling on this, we should probably discuss this on webkit-dev.

I would expect computePreferredLogicalWidth's code to be old and thus don't match our current style very well.

I pointed it out on webkit-dev: https://lists.webkit.org/pipermail/webkit-dev/2013-February/023947.html
