The permissions on the working directory are not surprising (except 
perhaps for the `+'), since the directory is created by fmtutil with the 
command

   (umask 077; mkdir "$tmpdir")

But on my system, running the latest snapshot, the files within that 
directory still get the expected 644 permissions.  I'm running Win7 in 
case that makes a difference.  At the moment I don't have access to an 
XP system to test this on.

I wonder if this has nothing to do with texlive or fmtutil, but is 
simply a problem with the ACLs on a directory created with umask 077. 
Corinna, are there changes in the 20100910 snapshot that could explain 
this?  And would there be a difference between XP and Win7?
