$ cat go.sum

...

What did you expect to see?

Only the two lines referring to module gioui.org/cmd.

What did you see instead?

A spurious line for gioui.org, which is not even a module, but rather the root repository for gioui.org/cmd.

When the Go command resolves gioui.org/cmd/gio to a module, it queries every prefix of that path in parallel and checks whether a package is present.

We need to verify the sums for these modules, but there's not really any point in saving sums for module zips that we don't end up using. We shouldn't add these to go.sum.
