Is it possible to shallow clone a specific commit in a repository, i.e. with depth 1? Something like

git clone http://myrepo.git 728a4d --depth 1

to get the repository state as it is at the commit with SHA 728a4d...?

The motivation is to avoid having to clone the whole repository, then check out that specific commit, when we're only interested in the state of the repository at that specific commit.

Starting with Git 2.5.0 (which needs to be available at both the client and server side) you can set uploadpack.allowReachableSHA1InWant=true on the server side to enable fetching of specific SHA1s:

git init
git remote add origin <url>
git fetch --depth 1 origin <sha1>
git checkout FETCH_HEAD

Note that I did not find a syntax to do this with git clone directly.
