Hi,

I opened issue #8215 about PyTuple_Parse*() outdated documentation. When I 
read the code, I found two functions: getbuffer() and convertbuffer(). 
getbuffer() checks that the buffer is contigious, whereas convertbuffer() 
doesn't. We can group formats by contigious check:

 - contigious buffer: s, y*, z*, w*
 - discontigious buffer: s#, y, z, t, w, w#

I tried to test formats accepting discontigious buffer but I didn't found any 
function or library to test this.

I'm not sure that functions using s#, y, z, t, w, w# format do really support 
discontigious buffer and it's just a bug in getargs.c.

Do someone have information about that? Should it be fixed (only accept 
contigious buffer)?
