I currently can only come up with the pragmatic approach of using a set
of filetypes to fake the execute permission bits. If we would go for it,
a short list of filetypes is preferred so trying to limit it to those
cases where it really matters. I think that's filetypes
representing/containing ARM code but I admit that's very arbitrary. Your
Obey filetype challenge is a good one, I'm not sure whether I can really
justify that.

Duncan, do you actually have usecases where the execute permission bits
matter ? Is this an issue for a certain port ? Or is this just found by
your testing ?

I can only imagine this being an issue for a ported shell, like bash.

John.
