[cairo] Don't print unobfuscated message IDs in your list archives

[Ryan Schmidt]

I notice that you're printing message IDs in your mailing list  
archives. For example the source of this page:

http://lists.freedesktop.org/archives/cairo/2006-July/thread.html

includes the following comment:

<!--3 01152124771/ 
F216A53F-3E22-4E7C-927F-96E46B7A65B6 at ryandesign.com- -->

I would appreciate it if you would not print things on your web page  
that look like (and are) valid email addresses at my domain, without  
obfuscation, because the spambots find them in no time and I end up  
receiving spam to them.

I'm pretty sure it's possible to configure Pipermail/Mailman to not  
output that, because the following Pipermail/Mailman installations  
don't do that:

Thanks.
