The patch description should describe what the patch does, not how bad 
the indentation loos in your email client.

I can't get the patch to apply.  Something is converting tabs to spaces, 
and I assume it is your email client doing that.  I recommend using the 
git send-email command to send the patches, after configuring your git 
to send emails via Gmail.  You can google how to do that, but here is a 
starting point: https://gist.github.com/jasonkarns/4354421
