### Please describe the problem.

When a git-annex is cloned from one where git init was run with --separate-git-dir, it works fine under Linux, but fails under Windows

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

This issue is not a show stopper. I otherwise love the concepts behind git-annex very much.
