This always perplexes me. I was cloning this
git clone https://android.googlesource.com/kernel/msm.git
And It seemed to be cloning resolving
Also, what happened on my system just now (windows 7). The automatic initialization (git init) did not take place during the
git clone URL
Operation. Also got the same succesful clone msg.
After I did a 'manual'
git init
The clone operation resulted in a dir with contents. After I repeated it.
So, just try a git init if a dir is empty after a git clone (and the master branch is not empty). Then repeat the clone.
