du counts soft links

but not

ln /home/brian/testdirectory/.a newname

hard links

say .a is 112 bytes,

our stat does not return link type but it looks like the real thing, and 
we count 112 bytes

du seems to see it as a real link and does not count it.... it seems

even ls does not show a hard link as a links..
