docs: def CanonicalPathToLocalPath(path):
    r"""Converts the canonical paths as used by GRR to OS specific paths.
  
    Due to the inconsistencies between handling paths in windows we need to
    convert a path to an OS specific version prior to using it. This function
    should be called just before any OS specific functions.
  
    Canonical paths on windows have:
      - / instead of \.
      - Begin with /X:// where X is the drive letter.
  
    Args:
      path: A canonical path specification.
  
    Returns:
      A windows specific path.
