Django templates, suppress newlines after each template tag in for loop

Django template system adds empty lines when displaying a list in for-loop. I am a bit confused trying to render this template: 

<h1>My log</h1>

<textarea>
{% for item in items %}
    {{ item }}
{% endfor %}
</textarea>

I expected:

<h1>My log</h1>

<textarea>
    * message line of text 1
    * message 
number 2 on multiple lines
    * message line of text 3
</textarea>

But I got:

<textarea>

    * message line of text 1

    * message 
number 2 on multiple lines

    * message line of text 3

</textarea>

Is there some way to suppress empty lines and get desired result?

I believe you're looking for the {% spaceless %} tags:

https://docs.djangoproject.com/en/1.8/ref/templates/builtins/#spaceless

<textarea>
{% spaceless %}
    {% for item in items %}
        {{ item }}
    {% endfor %}
{% endspaceless %}
</textarea>

But note that only space between tags is removed so you may need:

<textarea>
{% spaceless %}
    {% for item in items %}{{ item }}{% endfor %}
{% endspaceless %}
</textarea>

In fact the following might actually do it for you:

<textarea>
    {% for item in items %}{{ item }}{% endfor %}
</textarea>

If your item elements actually contain line breaks then you will need to strip them in some way before hand, either using a filter or in a model method or something.
