[Bug] pigar doesn't check if the dev dir is part of a bigger git repository.

[OlivierDehaene]

In reqs.py:_search_path

def _search_path(path):
    mapping = dict()

    for file in os.listdir(path):
        # Install from PYPI.
        if fnmatch.fnmatch(file, '*-info'):
            ...

        # Install from local and available in GitHub.
        elif fnmatch.fnmatch(file, '*-link'):
            ...

            # Check .git dir.
            git_path = os.path.join(dev_dir, '.git')
            ...
            
    return mapping

The git directory checking is sufficient for the best case scenario where the package's code is next to the .git directory. However if your package is part of a bigger git repository, the checking fails because git_path doesn't exist.

One of the potential way of solving this issue would be to write a similar logic to what pip does, a subprocess call to git rev-parse --git-dir. See: this line.

If adding pip to the dependencies is not an issue, using pip._internal.vcs.git.Git directly for the full git logic could be another option.
