I’ve gone away and had a look, then come back and had a think. This has resulted
in 9ce7802. Since we just have to worry about suid/sgid (as :tangle-mode is only
applied to the file produced [with the sticky bit being dir-specific]), not much
is required — we just allow the `s' in place of `x' for the user/group 
executable
flag.

This is pretty trivial as we’re still relying on `file-modes-symbolic-to-number'
for this, and in a very straight-forward way. So, I think we should be fine now 
🙂.

All the best,
Timothy
