Option wrapping around Crate.module#83415Conversation
Now that we record the crate's name in its `clean::Item`, pushing the
crate name onto the `stack` causes duplicate paths. E.g., the URL
generated for the path `::foo::bar::baz` would be something like
../foo/foo/bar/baz
With this commit, the URL is corrected to
../foo/bar/baz
I'm wondering if it was originally there so that we could `take` the module which enables `after_krate` to take an `&Crate`. However, the two impls of `after_krate` only use `Crate.name`, so we can pass just the name instead.

Is there ever a case where this unwrap will fail? Why does fold_item return an Option anyway?

fold_item returns None if the itme was stripped. I don't think the whole crate can be stripped so this should be fine.

Seems like a future enhancement could be to store a Module instead of an Item. Probably we would need to add a few more fields to Module (like DefId and name) to do that.
The previous changes mean that we can now remove this `Option`.

It took me a second to realize: the reason this changed is because you partially moved out of krate when adding krate.module to the work list.

Yeah, I mentioned that in the PR description:

Right - that explains that it's possible, the krate.module thing explains why it's necessary. :)

Yeah, I should've included more information :)
