Jekyll/Liquid Relative URL filter breaks links

I'm trying to use relative_url in most of the links of my Jekyll theme, so if someone wants to have this theme working in a subdirectory he can do it. I have a problem with the list of categories of the post, each of which should link to the archive.

In _layouts/post.html I have this code:

{% if site.data.settings.categories.active %}
  {% include categories.html %}
{% endif %}

categories.html has this code: 

<div class="categories">
    <span><p>Categories:</p>
    {% if post %}
      {% assign categories = post.categories %}
    {% else %}
      {% assign categories = page.categories %}
    {% endif %}
    {% for category in categories %}
      <a href="{{ "/categories/#{{category | slugify}}" | relative_url}}">{{category}}</a>
      {% unless forloop.last %}&nbsp;{% endunless %} 
    {% endfor %}
  </span>
</div>

Here's the problem: 

 <a href="{{ "/categories/#{{category | slugify}}" | relative_url}}">{{category}}</a>

Somehow, this returns the current post url. 

<a href="/categories/#{{category | slugify}}">{{category}}</a>

This returns the correct link, but does not work in case the site is in a subdirectory.

Why it returns the post url?

There are multiple problems here.

First off, Liquid doesn't evaluate nested constructs. Therefore, the following code:

{{ "/categories/#{{category | slugify}}" | relative_url}}

needs to be rewritten into:

{% capture url %}/categories/{{ category | slugify }}{% endcapture %}
{{ url | relative_url }}

Secondly, there is no global post object. Therefore {% if post %} is always going to evaluate to a negative. i.e., it is redundant.
