My suggestion: Anchor in brackets before or after the link. So this: [Some link] http://example.com/ and this: http://example.com/ [Some link] would both become a link with "Some link" as the text. If there are brackets-text both before and after, choose the one after. This is unambiguous for almost all kinds of text, and anyone who is oblivious to the syntax is unlikely to stumble into it by mistake.
