rustdoc search fails to find some methods

[SimonSapin]

The Float trait has an abs method, but searching for abs currently fails to find it.

This appears to be working now, at least for the case of Float::abs.

Confirmed-- I can see std::num::Float::abs in the link posted in the description that goes to http://doc.rust-lang.org/std/?search=abs, so I think this should be closed since it's fixed already, @steveklabnik.

Hurray for being fixed!
