jekyll-relative-links doesn't update links in markdown

[ghost]

The official docs state that this gem/plugin is a default plugin that cannot be disabled. However, it doesn't appear to work at all when deployed to github or locally.

From the README.md:

What it does

Let's say you have a link like this in a Markdown file: [foo](bar.md)
While that would render as a valid link on GitHub.com, it would not be a valid link on Pages.
Instead, this plugin converts that link to: [foo](bar.html)

It's supposed to make relative markdown links work without modification when deployed to gh-pages. Some of the things that could be handled by this plugin are currently being handled by the docs gulp task.

foo.md and the adjacent bar.md are converted to foo/index.html and bar/index.html respectively by the Jekyll build process.

A relative link in foo.md must refer to bar/index.html by ../../bar thus the normal ../bar.md and/or simply bar.md must be converted for links to work properly.

TL;DR

This link conversion process adds some (would be) unnecessary complexity to current build scripts. It would be better if we could get this plugin to work to simplify things.

Relevant Issues:

• Support relative links with both markdown as well as jekyll  github/pages-gem#69
