[PATCH] emacs: get rid of trailing spaces in notmuch-hello view

[Dmitry Kurochkin]

Hi all.

I am going to remove needs-review tag from this one since there seems to
be no one interested in reviewing it.  The patch itself may not be
trivial, but it is pretty simple and does not make any critical changes.
So I believe it is safe to push it.  If there are any issues with the
patch discovered later, I am committed to fix them.

Regards,
  Dmitry
