Sorry but I still can't apply your patch :(. I think you accidentally
added a trailing space character (at the last line).

Perhaps it's a good idea to send the patch to yourself, download the
email and try applying if it works, before sending it out.

Best regards,

If you use one less tab, you will not go over the 90 column limit,
right?

Only 1 tab is needed.
