Broken link detection if link text contains bracket

[evgeny-sureev]

Example:

[It's a link, but it won't be (converted) to NSAttributedString.Key.link](https://google.com)

[ivancantarino]

Usually links need to be like this:

[Google] (https://www.google.pt) without the space

If you use it without the https://, or without the www it won't work.

This is indeed a problem, even though the example cited should really be using literal escapes for the parentheses. See issue #7.

This should be fixed in 1c489af. I'm going to leave this issue open and do some more real world testing, but if you'd like to try it out yourself, go for it!
