Add note about https://tahoe-lafs.org/trac/tahoe/ticket/1572 not working.
Note: having "Tahoe-LAFS" be the full public name of the project is great (since "Tahoe" by itself is hard to search for), and having "tahoe-lafs.org" be the hostname for the project is great (because "tahoe.org" is probably owned by some car company or ski resort). But of course, when talking about it, we use just "tahoe" as an abbreviation. And I don't think it's necessary to make every single directory and URL component spell out the full name. There are a growing number of symlinks and URL rewriting rules to replace "tahoe" with "tahoe-lafs" on the web site, and I think those are going to eventually drive us completely insane. So let's avoid changing anything if we can, identify which URLs have been around the longest, and make them work without introducing new variants.
