Switch to using relative paths to the git repository.
This allows the git repository to be moved while git-annex is running in it, with fewer problems. On Windows, this avoids some of the problems with the absurdly small MAX_PATH of 260 bytes. In particular, git-annex repositories should work in deeper/longer directory structures than before. See http://git-annex.branchable.com/bugs/__34__git-annex:_direct:_1_failed__34___on_Windows/ There are several possible ways this change could break git-annex: 1. If it changes its working directory while it's running, that would be Bad News. Good news everyone! git-annex never does so. It would also break thread safety, so all such things were stomped out long ago. 2. parentDir "." -> "" which is not a valid path. I had to fix one instace of this, and I should probably wipe all calls to parentDir out of the git-annex code base; it was never a good idea. 3. Things like relPathDirToFile require absolute input paths, and code assumes that the git repo path is absolute and passes it to it as-is. In the case of relPathDirToFile, I converted it to not make this assumption. Currently, the test suite has 16 failures.
