OK; I've now fixed recent breakages so that we can access
https://аррӏе.com again.

Now the question is...  what do we do about this in the network security
manager.

If you go to that domain in Firefox, for instance, it won't say that
there's anything wrong with it...  because it isn't.  It's a totally
normal domain name consisting of ASCII characters and a CYRILLIC SMALL
LETTER PALOCHKA instead of the L.

`puny-highly-restrictive-domain-p' is not triggered for the domain, so
eww doesn't signal anything wrong with it, either.

So...  Do we say "fine, this is all fine" or do we ... do something?
:-)  Opinions welcome.
