There's a formatting problem in Doc/library/multiprocessing.rst due to consumption of the backslashes in multiple steps. The following keeps all of the required backslashes in the HTML output:

    * An ``'AF_PIPE'`` address is a string of the form
      :samp:`r'\\\\\\.\\pipe\\\\{PipeName}'`.  To use :func:`Client` to connect to a named
      pipe on a remote computer called *ServerName* one should use an address of the
      form :samp:`r'\\\\\\\\{ServerName}\\pipe\\\\{PipeName}'` instead.

Or just use a regular literal and rely on the reader to understand that "{PipeName}" and "{ServerName}" are parameters:

    * An ``'AF_PIPE'`` address is a string of the form
      ``r'\\.\pipe\{PipeName}'``.  To use :func:`Client` to connect to a named
      pipe on a remote computer called *ServerName* one should use an address of the
      form ``r'\\{ServerName}\pipe\{PipeName}'`` instead.
