It’s better to not have repeated ) { characters to confuse code editors. How about this instead?

                if (textAlign == JUSTIFY && r != trailingSpaceRun
    #if ENABLE(CSS3_TEXT)
                    && style().textJustify() != TextJustifyNone
    #endif
                ) {

Does this really need to be done down here at such a low level? Can’t we change the textAlign value at some higher level instead?

I tried to satisfy the style-checker, that's why I did it this way. Probably the best would be to file a bug against it, and use the simpler version. Do you agree?

I'll take a look at this.

I agree with Darin, but other than that, unofficial r=me as well.

I moved the logic up into "RenderBlockFlow::textAlignmentForLine".

We intentionally put the short half of the #if first for easier readability, which is why the !CSS3_TEXT branch came before the #else instead of the other way around. I'm a little disappointed to see that changed in a patch that doesn't give any rationale for the change.

Extra space here after the "&&".

It seemed easier my to read the other way. I'm going to update it in a follow up patch to be consistent with the rest of the code. I will CC you.

And will remove the extra space.
