This is still not working :-(.
One patch per email is not very useful: our cfbot is not smart enough
to realize that this is meant as a set of patches rather than a series
of updated versions of a single patch.
Also, I'm not quite sure what you are doing but it is not ending up as
an attached file. It really needs to be an attachment, not inline
text, so that it can be conveniently saved and won't get mangled by
anyone's mail reader.
You could make it work by attaching several patch files to one email.
But for a patch set as large as this, it's probably a better idea
to put the patch files into a tar.gz file and send that as a single
attachment.
