[issue24278] Docs on Parsing arguments should say something about mem mgmt for formatters returning C strings

[Martin Panter]

Martin Panter added the comment:

Here is a patch.

Looking at the code, s#, z#, y and y# are the conversions that call convertbuffer(). These require that the object does not have a PyBufferProcs.bf_releasebuffer() method, which guarantees that the buffer’s lifetime is the same as the underlying object.

In the patch I also removed a contradictory notice about nulls with the “u” conversion.
