Shallow checkouts

[germanysources]

Shallow checkouts are currently not working

 git clone --depth 2 https://saphost/sap/zabapgitserver/repo.git

gives a fatal error.
fatal: expected shallow/unshallow, got NAK
fatal: The remote end hung up unexpectedly

and pushing a shallow checkout to abapGitServer causes a runtime error in the backend.

@larshp
No. it has low priority. I can always work around with a full clone.

@germanysources off topic, but can these two branches be deleted? https://github.com/larshp/abapGitServer/branches
