Removed slash between site.baseurl and post.url

[thde]

I think there shouldn't be a slash between {{ site.baseurl }} and {{ post.url }}:

If the theme is used on the root path, it will create a url like //my-post

👍 This is what the Jekyll docs recommend for GitHub Pages:

When doing permalinks or internal links, do it like this: {{ site.baseurl }}{{ post.url }} – note that there is no slash between the two variables.

Please merge! I think quite a lot of people are hitting this bug.

I agree! Please merge it. It caused me quite some time to figure out what was wrong since this is my first time with jekyll. :(
