Dash tags -%} remove space between tags in an unexpected way

[tdelmas]

{% macro dash(a) -%} {{ a }} {{ a }} {%- endmacro %}
/{{ dash("_") }}/

Produce /_ _/ as expected (no spaces outside, one inside)
But :

{% macro dash(a) -%}{{ a }} {{ a }}{%- endmacro %}
/{{ dash("_") }}/

Produce /__/ (no space outside, an no inside)

It that the expected behaviour ? "If the tag with tash is not followed by a space, then stip spaces after the next one"

I think your code might be being mangled by the markdown parser. Can you put it all in ``` block code tags?

I've updated it.
You can see the same behavior here : http://www.raymondcamden.com/demos/2014/oct/15/test.html

{% macro word(w) %}{{ w }}{% endmacro %}

{% if 1 -%} {{ word('EVERYTHING')}} {{word('FINE')}}{% endif %}
{% if 1 -%}{{ word('SOMETHING')}} {{word('WRONG')}}{% endif %}

Do not forget to put {} in the JSON part of the webpage.

EVERYTHING FINE SOMETHINGWRONG

To clarify the result : there was a space between "SOMETHING" and "WRONG" but the dash (-) removed it.
