Subject: emacs: Improve `notmuch-hello' display on ttys.
X-Git-Tag: debian/0.12_rc1-1~220
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=38546e4acba5593c6ad8b35712475abc27d3a4fd;p=notmuch.git

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

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.
