Error when usage documentation uses qualified names

[klmr]

I’ve got a package that isn’t supposed to be attached. The documentation of functions makes this explicit by showing the @usage with a namespace qualifier:

#' …
#' @usage
#' pkg::func(args)

This causes pkgdown::build_site() to issue the following error:

Error in fun_info(x) : Unknown call: ::

Indeed, pkgdown:::fun_info (or rather, functions further upstream, parse_usage and usage_type) fail to handle qualified function calls. I’d love to contribute a PR but I’m unsure where and how best to handle this case.

Could you please build a minimal package that recreates the issue?

Here’s a zip of the package: test-0.0.0.9000.tar.gz
