I believe that the thing about closing parentheses actually does happen.

See also tip number 7 on the tips and tricks page. I agree it would be nice automatically encode some characters in links in comments, but it would be pretty hard to get it right. For example, consider the following comment:

Google (http://google.com) is a good place to search for things. You may also want to check Wikipedia—at http://en.wikipedia.com—when you're searching for stuff before asking your question on http://mathoverflow.net.

In a dumb algorithm, the closing paren would get included in the google url, the em-dash in the wikipedia url, and the dot at then end of the MO url, all of which would break.

The problem is that that dash is not a dash but an en-dash, a.k.a. U+2013 EN DASH, which is not an allowed character in an URI. It should be percent-escaped (ideally automatically by something...)

If markdown or html worked in comments, this would be much less of a problem.

They get messed up.
