Docs for vendored packages?

[Alex Buchanan]

Does anyone have a strategy for accessing the docs (godoc) of vendored dependencies?

I was a little surprised to find that godoc decided not to show vendored packages, here:

https://github.com/golang/go/issues/13929

This also applies more generally than vendored deps. In the past, I have found myself wishing I had easy access to docs of older go versions.

Thanks.
