No, they're not.
I moved the '#!' check outside of the get_file_attribute test entirely.
I had originally moved the .exe check outside of the block but that didn't
make any sense, in hindsight, since it just forced cygwin to report .exe
files as executable when windows couldn't actually execute them.
This is not the problem for '#!' scripts, however. Cygwin can execute
them regardless of whether ntsec or Windows thinks they're executable
or not.

It's not just "mode display". It affects whether a script will be
executed or not.

That is exactly what the change does. This isn't just for display.
We've made ntsec the default but there are possibly a number of people
out there who have never done a 'chmod a+x foo' on their shell scripts.
Until we have a consistent story on how to solve their problems, I think
it makes sense to make '#!' always executable.
I'm willing to be swayed on this but, so far, it doesn't seem like anyone
is effectively communicating with anyone else here. We need to get on
the same page wrt the problems and how we are going to solve them.
