The idea here is that when this is done interactively the user will be aware of
the URL this is being applied to, and so it isn’t a risk. Let me know if this
assumption doesn’t hold.

Mmm. I could add `-policy' to that variable name perhaps.

Well, the thing here is that I’m explicitly trying to mimic the
file-local-variable dialog, and since a general form isn’t exposed by Emacs, a
little bit of proliferation seems like the best option to me.

Ok, that is not the intended behaviour. I’ll see if I can work out what’s going
on here. Oh, and I should change that comment to “Set up the contents of the *Org
Remote Resource* buffer.”.

Hmm, the “skip” action isn’t determined by the “is it safe” functions, but some
wording that doesn’t sound completely safe at least would be good.

My initial reaction is that this feels like overkill.

All the best,
Timothy
