I guess I have to agree.  It's too ugly to live like this.  Unless there
are objections, the party line will be "either chmod your files or
revert to nontsec".

I'll put things back the way they were, more or less modulo some
formatting fixups.

I hadn't really changed anything from the prior implementation other
than to move the test for '#!' out of the get_file_attributes != 0
condition.  The file is certainly readable if you've just figured out
that it began with '#!' by reading the first two characters.

Thanks for helping to think this through.

I guess we're back to making some kind of change in setup.exe or
telling people exactly what they need to do to fix their system
in some kind of document or popup.  A post-install script could
easily popup a message if required.
