Here is a more complicated example, since the above does technically have an
alternative fix:

sockobj.sendmsg(buffers[, ancdata[, flags[, address]]])
->
sockobj.sendmsg(buffers, ancdata=None, flags=0, address=None)

As far as I understand you should convert these with the "optional group" syntax
(i.e. brackets).

That's correct. Functions that use PyArg_ParseTuple should continue to use PyArg_ParseTuple. Ryan: add a "/" on a line by itself after the last parameter of each of these functions, and that will let you use the [ ] syntax too. Please see the Argument Clinic howto for more.
