This was my first suggestion, unfortunately it shows up broken behaviour 
in all but the latest version of cpio. It creates 0700 directory 
permissions which is even worse.

I didn't find the later versions of cpio to be widespread, so I wrote the 
patch to work in all cases.

See the thread 'git-clone file permissions and cpio'.
