I always use 80-cols, everywhere.  Not because I particularly like it -
I find it a bit too small.  I use it because it is the standard, and
using it helps me see where and how badly we violate the standard.

We've actually done pretty well - linewrap in 80 cols rarely causes me
problems.  It's sufficiently rare that when it *does* happen, it really
stands out.

IOW, the changelog is quite the exaggeration.

I think that's going too far - 96 will be enough and it's a multiple of 8.

The multiple-of-8 thing seems pleasing but probably doesn't matter
much.  It means that things like


if (foo) {
	if (foo) {
		if (foo) {
			if (foo) {
				if (foo) {
					if (foo) {
						if (foo) {
							if (foo) {
								if (foo) {
									if (foo) {
										if (foo) {
											if (foo) {
												if (foo) {
													if (foo) {
														if (foo) {
												

will line up properly.


If we really want to improve the world we should jump into a time
machine and set tabstops to 4.  Sigh.
