Obviously, somewhere in the mediawiki software there is a list of non-whitespace characters which can follow the end of a link and still be part of it.
I think *any* non-whitespace characters will be included in the link. Excluding punctuation might be a good idea. I can't see a good reason for including the "'s" in the link, I think it looks better without, even when it isn't ambiguous.
