This patch seems to have been horribly whitespace damaged.

Have you seen "git send-email" ? It's very useful for avoiding this sort
of thing and also takes a lot of the grunt work out of reposting a
series.

It also chains the patches as replies to the introductory zero-th mail
-- which is something I've been meaning to ask you to do for a while.
It's useful because it joins the series together in a thread which makes
it easier to keep track of in my INBOX.

Ian.
