Allow free link urls to end with a slash

Another minor bug. If a URL isn't in [[ ... ]] brackets (a free link) and it ends with a slash, the slash isn't part of the URL.

This makes it look a little odd, especially if you are using different font sizes for links. Can the regex be relaxed a bit so that the entire URL is linked?

Here is a simple patch:

Relax free_link regex to allow urls to end with a slash.

Applied, thanks. I guess I just copied that list of punctuation characters from other patterns, didn't notice that slash makes more sense as part of the URL. – Radomir Dopieralski
