Thanks for the memoryview tip - I though I was up-to-date with python's
features but obviously I wans't ^^ (I searched through dict views but
that wasn't it...)
It should be exactly what's needed to replace these unnecessary
additional arguments.

As for the simple doc update, I was just pointing out the fact that EOF
is reached if read methods returns an empty bytes AND we didn't ask for
0 bytes. Just to avoid confusing people : file.read(0) will always
return an empty bytes, but it doesnt mean that we're at eof, contarrily
to what the doc currently says B-)
