rustdoc: word wrap CamelCase in the item list table
This is an alternative to ee6459d6521cf6a4c2e08b6e13ce3c6ce5d55ed0.
That is, it fixes the issue that affects the very long type names
in https://docs.rs/async-stripe/0.31.0/stripe/index.html#structs.
This is, necessarily, a pile of nasty heuristics.
We need to balance a few issues:
- Sometimes, there's no real word break.
For example, `BTreeMap` should be `BTree<wbr>Map`,
not `B<wbr>Tree<wbr>Map`.
- Sometimes, there's a legit word break,
but the name is tiny and the HTML overhead isn't worth it.
For example, if we're typesetting `TyCtx`,
writing `Ty<wbr>Ctx` would have an HTML overhead of 50%.
Line breaking inside it makes no sense.
