Documenter.Utilities.url returns wrong path when repository is git submodule

function url(repo, file; commit=nothing)

I'm developing a Julia project as a git submodule of another repository. When doing this, Documenter.Utilties.url appends an unneeded subdirectory into the path.

For example, Documenter creates this link:

https://github.com/user/project.jl/blob/{commit}/submodule/src/filename.jl#L1-3

when the correct link should be

https://github.com/user/project.jl/blob/{commit}/src/filename.jl#L1-3

Note the extra /submodule/ in the path.

I believe the problem is in the following lines, which construct the path:

    file = realpath(abspath(file))
    remote = getremote(dirname(file))
    isempty(repo) && (repo = "https://github.com/$remote/blob/{commit}{path}")
    path = relpath_from_repo_root(file)
