[PATCH 2/2] getlines: last line of file should always have a newline

From: Jakob Kramer <jakob.kramer_AT_gmx.de>

This is a useful behavior if you want to reorder the lines,
because otherwise you might end up with originally two lines
on one, e.g.

        $ echo -ne "foo\nbar" | sort
        barfoo
