If a link looks like this [./example](./example), current implementation will return [https://raw.githubusercontent.com/example](./example), which is not the expected behavior.

Can you please double-check if we could fix/improve the regex above? generating new (${path}) seems hacky to replace while haven't tried it locally... Also what is a sample README URL we can test against?

[Barbapapazes]

Yes, here some readme where there is the issue: #68 (comment)

I've updated the regexp to simplify code and avoid too many if.
