So that’s about 450,000 fewer lines of code in the codebase…

That’s about 450,000 fewer lines of *boilerplate* in the codebase :)
And with HG you download the entire history, so… it’s not actually any smaller. Still cool though.
But for tar and other things it’s better. Also 450k lines less to parse should boost a little bit compile times. I’m wondering how much compile time is gained by just this change.
The new headers are so short, it’s *weird*. But I’m sure I’ll get used to it :)

Not enough to matter. The preprocessor spends (or, now, doesn’t spend) a couple of clock cycles per character looking for where the comment ends, and that’s it. It’s like trying to improve the speed of a dump truck by scraping off some of the paint to cut down on weight. Technically, any physics major can tell you that, on paper, you *can* make the truck weigh (a little) less by scraping off paint, and technically the truck’s weight *is* relevant to how fast it can go, but in practice you’re fundamentally not going to change its speed in any way that matters by scraping off a little paint.
The real advantage is that people who are looking at the code (and don’t happen to have kill-a-lawyer.el or something similar installed) no longer have to scroll past all that.
