share: host the git repository alongside the store Before this changeset, the internal git repository were always stored in '.hg/' even when the repository was a 'share' of another one. With this patch, hg-git respect the '.hg/sharedpath' file and stores the internal git repository and associated caches in the original repository. This allows multiple 'shares' to use the same git repository. This does not affect the 'intree' variant where the repository is directly stored inside the working copy.
