Hey Allistair,
that paragraph looks like it was buggy - it should have had
test1.txt followed by a single nul and then twice MAXPATH
nonnulls and then a double nul, like the similar tests I fixed in
http://www.winehq.org/pipermail/wine-patches/2008-May/055371.html
As it is, there's no way FO_DELETE could see test1.txt to maybe
delete it.

James, do you agree?

Perhaps you could leave it enabled if you fixed it like the
ones I fixed.  (Or tried to fix; sadly, Alexandre hasn't
committed it yet. Why?)
