Looks like only one way to me, the centering just moves the "code" text to the middle, but it is still allowing the click anywhere on that top line/header (...)
Yup. The below excerpt is from the patch PM:
One little quirk is that that div has more horizontal extent than the header text, so, while people will tend to think of this feature as being tied specifically to the header text, it actually affects all of the space immediately above the contents of a [code] block (which, accidentally, will probably help discoverability).
Good to see you still around PG, I thought about you not too long ago (...)
Yep. I'm still kind of around... I thought about you, too, recently.
(I was looking at the Merit Poker code the other day, which I haven't touched in a little over a year, and I gave myself the giggles pretty good listening to the audio for the /virus easter egg, and that "Wilhelm scream" that plays when someone goes bust.) 
I do miss this place. Unfortunately, it still makes just as much sense for me to throw myself at Bitcointalk as it did ~4 months ago when theymos and I arrived at the decision to part ways (which is to say: it doesn't make much sense at all). But, old habits die hard, and I expect I'll continue to once-in-a-while get an urge to contribute something (sometimes those improvements will be announced, like with this small code-selection patch, and sometimes they'll be too insignificant for that, like with the very small ignore-related bug I fixed at around the same time).
(I don't want to turn this post into a diary entry, but in case anyone is wondering what I'm spending my energy on these days: I've more-or-less focused my attention back on an old
PLT-related idea that I was pursuing just before I joined Bitcointalk. I really enjoy working on compilers and so on, and they often present really interesting problems, especially when I approach them in the dependency-free, self-hosted, trusting-trust-proof way that I've been closing in on for the last 15 years or so. I was thinking of occasionally sharing/posting-about some of the bootstrapping problems that I've bumped into, and how fascinating and fundamental their solutions can be, but I don't think that there's much of an audience for that kind of exposition nowadays. Even before AI, I struggled mightily to find fellow programmers possessed of any serious desire to make use of and build nothing but deeply-understood things. I struggled even to just find people who were willing to think critically about the sacrifices that they had been taught to make at the altar of productivity. In the AI age, the "comprehension optional" style has really taken root, and that school of thought is anathema to someone like me. So, instead of depressing myself further by trying and failing to find the few remaining members of my tribe, I'll for now just quietly pursue my interests and keep the bulk of my thinking unshared.)
