We're about to change git-clone(1) so that we set up the reference
database at a later point. This change will cause git-remote-curl(1) to
not detect the repository anymore due to "HEAD" not having been created
yet at the time it spawns, and thus causes it to error out once it is
asked to fetch the references.
We can address this issue by trying to re-discover the Git repository in
case none was detected at startup time. With this change, the clone will
look as following:
1. git-clone(1) sets up the initial repository, excluding the
reference database.
2. git-clone(1) spawns git-remote-curl(1), which will be unable to
detect the repository due to a missing "HEAD".
3. git-clone(1) asks git-remote-curl(1) to list remote references.
This works just fine as this step does not require a local
repository
4. git-clone(1) creates the reference database as it has now learned
about the object format.
5. git-clone(1) asks git-remote-curl(1) to fetch the remote packfile.
The latter notices that it doesn't have a repository available, but
it now knows to try and re-discover it.
If the re-discovery succeeds in the last step we can continue with the
clone.
