描述
Jinja has a useful feature where you can strip out whitespace that you've added to make your template more readable:
{% for item in seq -%}
{{ item }}
{%- endfor %}
This will yield all elements without whitespace between them. If seq was a list of numbers from
1to9, the output would be123456789.

In other words, adding a - to get -%} will indicate that all whitespace should be removed between the for/if/other statement and the next character.
Feature request: any interest in adding this to Selmer?
