(I forget if this was posted here last year, it sounds familiar.)
Some of us are relatively new to the list...
Suppose I get a PGP-signed flaming message, full of insults, and at the end it says, sarcastically, "For a stupid moron, you've made some very nice postings." I could choose to excerpt this last part, "...you've made some very nice postings", and exhibit it in signed form. What I would do
In other words, you'd like to retain an excerpt from the message with the signature still intact? Problem with that is how do you prevent one from creating a clerverly made excerpt that distorts what one is saying (but has a valid signature)? It seems your example does this very thing. Better to quote the unsigned portion but retainthe original signed message as evidence that the excerpt is Ok. [ Snip! ]
The checker would know he was dealing with an excerpt, and that it came from the end of the message, but he would have know way of knowing what was in the part that was removed.
That's the problem, of course.
