linkchecker is not catching some broken links

[jyn514]

https://doc.rust-lang.org/nightly/std/primitive.slice.html#method.concat-2 links to https://doc.rust-lang.org/std/primitive.slice.html#method.concat, which does not exist in the build directory, only on the website itself (it's linking to the stable docs instead of nightly).

Source code:

rust/library/alloc/src/slice.rs

Line 671 in 50a9097

/// Helper trait for [`[T]::concat`](../../std/primitive.slice.html#method.concat).

I expect this will break when promoted to the stable channel, it only works by coincidence now. I think it works because ../../ on the root directory stays as the root directory.

Hmm, I'm not actually sure this can be fixed without intra-doc links: Concat appears in std::slice::Concat which does need both ../../. I guess since this is harmless it doesn't actually need to be fixed?

cc #63351

This can be fixed after the beta bump now that #80181 is merged.

Is this still an issue?
