I recently forked the repository to build my own personal website. Everything was going smoothly until I tried to add 2 new pages. The first page was a markdown file, and the second was an html file that used Liquid tags. However, when launching the site with jekyll's server (bundle exec jekyll serve), I noticed that all of the markdown and liquid templates were rendering on the page without being processed, as if the content matched the source files.

After digging for a while, I realized that the file _includes/header.html assigns the content variable to page.content.

This overwrites Jekyll's intended purpose of the global content variable, which is to represent the rendered version of a page's content.

... the rendered content of the Post or Page being wrapped. Not defined in Post or Page files.

So I am curious if there is any reason for overriding this variable? It may cause others the same headache. I have removed the assignment from my fork and have not yet seen any side effects. I am happy to open a PR if it is indeed unneeded.
