Rustdoc on private crate gives infinite redirect loop #18715
Description
While looking for a different rustdoc bug, I found that the following lib.rs
#[test]
fn it_works() {
}
trait Y{}
impl Y for Option<uint>{}
(cargo new foo followed by adding a trait and an impl to the lib.rs)
produces the following doc/lib/index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="refresh" content="0;URL=../lib/index.html">
</head>
<body>
</body>
</html>
which is just an infinite redirect.
While the crate being empty (externally, due to all private items) means that rustdoc is pretty useless to run, I don't think it should fail into an infinite redirect, which is just confusing.
This doesn't happen if I replace Option with a struct defined within the same crate.
