    Determines the number of revisions in this repository.

    Parameters
    ----------
    sha : bool
        If True, the full SHA1 hash will be returned. Otherwise, the total
        count of commits in the repository will be used as a "revision
        number".

    show_warning : bool
        If True, issue a warning if git returns an error code, otherwise errors
        pass silently.

    path : str or None
        If a string, specifies the directory to look in to find the git
        repository.  If `None`, the current working directory is used.
        If given a filename it uses the directory containing that file.

    Returns
    -------
    devversion : str
        Either a string with the revsion number (if `sha` is False), the
        SHA1 hash of the current commit (if `sha` is True), or an empty string
        if git version info could not be identified.
