[PATCH] emacs: Improve `notmuch-hello' display on ttys.

[David Edmondson <dme@dme.org>]

Inserting spaces to pad out columns is good, except when the padding
makes the line wider than the window. This looks particularly bad on a
tty where there is no fringe.

Hence, avoid padding the last column on each row.

Thanks to j4ni in #notmuch for spotting this.
