    [PATCH rev-list.c] max-count in terms of intersection
    
    When a path designation is given, max-count counts the number
    of commits therein (intersection), not globally.
    
    This avoids the case where in case path has been inactive
    for the last N commits, --max-count=N and path designation
    at git-rev-list is given, would give no commits.
