I'm sorry, the actual revision is r85970.  Why should it be irrelevant for 
other branches?

That revision is actually an edit to re.rst.

Is the patch irrelevant for other branches?

[issue10198] wave module writes corrupt wav file for zero-length writeframes

[David Barnett]

New submission from David Barnett :

If the first call to writeframes happens to take an empty string as the data to 
write, then the next call to writeframes writes a 2nd header into the file, and 
forever after fails to patch the data length correctly.
