So... Does Alcatel-Lucent have a problem with AppleWebKit
users on principle?

It looks to me as though my problem with browsing around
under http://plan9.bell-labs.com/sources/ (and other subpages)
is because the server doesn't like the User-Agent string:

$ telnet plan9.bell-labs.com 80
Trying 135.104.24.16...

And here it is again w/o the User-Agent string:

$ telnet plan9.bell-labs.com 80

[... proper body returned...]

I tried playing around with the UA value and found that if I change
AppleWebKit to something else such as AppleWebKis I get a
response...
