It does. Actually, I've just checked, both current n-m and ifupdown
from wheezy support only 'source' directive. The difference between
source and source-directory is that the second form doesn't need a
glob mask to be specified, as it uses run-parts-style matching. In
that case, maybe it's better to change this to:

source /etc/network/interfaces.d/*

(The other utility parsing interfaces is guessnet, it's current
version also supports "source" keyword only.)
