Search result links on http://doc.rust-lang.org sometimes 404

[carols10cents]

I'm not exactly sure what's going wrong here, but this is what I did:

• Go to http://www.rust-lang.org/
• Click on Nightly API Docs, which goes to http://doc.rust-lang.org/std/index.html
• Search for replace
• Click on the result for regex::Regex::replace, which goes to http://doc.rust-lang.org/regex/enum.Regex.html#method.replace
• This gives me a github pages 404.

This appears to be isolated to the regex, getopts, log, and time crates, I tried to reproduce this with every crate and I got 404s when doing the following searches on the following results, but not for results from the other crates:

• search for replace, click on regex::Regex::replace (or any other regex::* result)
• search for opts, click on getopts::getopts (or any other getopts::* result)
• search for debug, click on log::DEBUG (or any other log::* result)
• search for time, click on time::Tm::asctime (or any other time::* result)

What's weird is if I try to reproduce this locally by doing:

• cd to my rust checkout
• $ open doc/std/index.html
• Search for replace
• Click on the result for regex::Regex::replace, which goes to file://[my rust checkout]/doc/regex/enum.Regex.html#method.replace
• This works fine! I see the doc page I expect!

I also found these other cases of 404s, which might be separate issues-- I'm happy to file them if someone agrees:

• In the results for a search for opts, the result for rustrt::task::TaskOpts goes to http://doc.rust-lang.org/rustrt/task/struct.TaskOpts.html which gives me a rust 404 page (the one that directs you to search ddg, the reference, or the docs).
• The sidebar link to the regex_macros crate (http://doc.rust-lang.org/regex_macros/index.html) gives me a github pages 404, and the sidebar link to rustrt (http://doc.rust-lang.org/rustrt/index.html) gives me a rust 404.

Now that the regex, getopts, log, and time crates are officially hosted on the rust-lang organization, I've tweaked the rules for how their documentation is accessed, causing these errors. The hyperlinks out into them from the main documentation probably just need to be removed, so we should stop generating documentation for these crate most likely to prevent the links from going all over the place.

The problem's still there.
You can search is, first line is std::Any::is, click it and you get 404.
