A meta-post: question came up recently here about how newsreaders (the software you're using to read this post) handle long URLs, like this one:
But this is on the sending end. The question is whether such links get split up when they're read.
If your newsreader splits this URL, could you post here and say what your newsreader is?
And what about Google Groups readers? I assume that GG preserves such links, but don't know for sure.
