Just to clarify my thoughts on this..
I feel that the tilde option is the worst choice. It's not an obvious underscore marker, isn't widely used (which should say enough) and I'm wondering if it wouldn't be a bad choice considering keyboard layouts.
Using the underscore characters would be second worst. The fact that it "is tradidtionally used to mark italic text whenever italics are not technically available" by authors is irrelevant in my opinion. Most users are probably unaware of that tradition and would probably find it an unintuitive marker.
My primary choice would still be the slashes.. the earlier comment that URIs should be matched on ":" is spot on and would remove any confusion with regards to URIs and italics.

Shall we mark it as "rejected" somehow? Just for book keeping...

Agreed, I took the liberty to put a comment box on the top of the page.

<rant>I prefer ISO-modified like 2007-Jan-11 because we all speak English here and since I've lived in North America and Europe, I often get confused as to which number is the month and day. Actually, maybe that's a standard ISO format as well, I'm not sure. I would also venture to say that the vast majority of people understand the twelve English month abbreviations... probably more than those who would get confused by not knowing if a number is the month or day, even though technically it is unambiguous.</rant>
