Actually, it's going to be the same thing with Git, the ".git" is one
level higher than the package which is passed to Version() in this case.
Version() can still run "git describe" or the like to get the latest
changeset number but:

* it's probably going to launch the "git" command which might be costly
* if for some reason the package is not from a Git repository, but
  there's one (potentially completely different) in a parent directory,
  "git describe" will happily return the changeset number from this
  upper directory and it's going to give some funky revision number.
