gitdot-cloned repo config lacks remote."origin".fetch

[smammy]

For reasons I haven't investigated, my ~/.dotfiles/config files are missing a fetch option for the "origin" remote. Here's the config for my clone of gitdot itself:

[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = https://github.com/smammy/gitdot.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "main"]
        remote = origin
        merge = refs/heads/main

And here's the same file for a dotfiles repo cloned by gitdot:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = true
    excludesFile = .config/gitdot/exclude
[remote "origin"]
    url = https://github.com/smammy/dotfiles.git
[status]
    showUntrackedFiles = no
[branch "main"]
    remote = origin
    merge = refs/heads/main

The effect of this is that git doesn't create remote-tracking branches, so it can't show me anything in git branch -r and commits aren't labeled with remote refs in git log.
