+
+SANITIZE_ALLOW_PATH: Allow path separators and colons.

+SANITIZE_ALLOW_RESERVED: Allow reserved device names.
+Without this flag a reserved device name is renamed (COM1 => _COM1) unless it's
+in a UNC prefixed path.

+Without this flag if the sanitized filename or path will be too long an error
+occurs. With this flag the filename --and not any other parts of the path-- may
+be truncated to at least a single character. A filename followed by an
+alternate data stream (ADS) cannot be truncated in any case.
