unnecesary space in filter.template.html

[jorgemv]

That's not exactly an issue:

There is an unnecesary space in the filter.template.html file. As result, the documentation generated contains that space too at the beginning of the interpolation but not as well at the end.

The first screenshot shows the extra space on the code and the second one shows it on the generated page.

Thanks for noting this. Do you have time to submit a PR?
