Version canonicalization redirect adds a spurious trailing slash, resulting in 404

[kpreid]

I’m trying to programmatically generate links to the documentation of the latest compatible version of a library. This requires using a partial version specification, which docs.rs will redirect. However, when the link is to an item and not a module, the redirect incorrectly adds a trailing slash. For example, https://docs.rs/itertools/0.14/itertools/trait.Itertools.html (302) will redirect to

https://docs.rs/itertools/0.14.0/itertools/trait.Itertools.html/ (404)

instead of

https://docs.rs/itertools/0.14.0/itertools/trait.Itertools.html (200)

thank you for the report!

we had a bigger refactor that tried to unify all the different places where we generate & parse urls, and slightly different in all cases.

I'll have a look
