Basic comment, your email client corrupted the patch, wrapping the lines
and putting odd spaces at the front of the patch, making it impossible
to apply.  Try using 'git send-email' to fix this up, or fix up your
email client.

Also, your patch should not have the email header up there in it, that's
the sign that something went wrong.

try it again?

thanks
