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

shaddy@JAZZ2-W10 C:\slaveproj
> git annex get services
get services
  Unable to access these remotes: origin

  Try making some of these repositories available:
        615bdcd5-6a5e-4330-84a2-b6c30cb3e5e4 -- shaddy@jazz2-w10:C:\masterproj [origin]
failed
git-annex: get: 1 failed

What steps will reproduce the problem?

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.
