The second one will remove the white space after it. As the document says:

You can also strip whitespace in templates by hand. If you add a minus sign (-) to the start or end of a block (e.g. a For tag), a comment, or a variable expression, the whitespaces before or after that block will be removed:
{% for item in seq -%}
    {{ item }}
{%- endfor %}
This will yield all elements without whitespace between them. If seq was a list of numbers from 1 to 9, the output would be 123456789.
