But you've used the W-word... :D
I'm for keeping it alphabetical too, I just didn't want to be that
pedantic.
I haven't ever seen an issue with the order of headers, but that
doesn't say much, I haven't seen much of a variety of systems. I'd
think it would be an issue with the headers themselves and wouldn't
expect that on modern systems though.
