Sigh.  Is this some sort of contest to see how many things we can
do wrong in a single patch?

- Include a changelog

- Include Signed-off-by:

- Don't use attachments

- If you _must_ use attachments, use text/plain, not application/octet-stream

- Format code to remain within 80 columns.

- Don't do "if(".  Do "if ("

Oh well.  Good to hear that the oops got fixed, thanks.
