depend.awk update

Browse Source 
cppregex.cpp recently had `#include "extern.h"' added as the last
quoted include.  That gets set to "" while collecting dependencies,
then preceded by a space when output.  So the unexpected trailing
space was new and wasn't caused by a change of awk versions as I
was suspecting.  This removes it.
