Filters are not applied in an include tag

[Vincent Foley]

With the extends tag, you can do the following (trivial filter used for example purpose):

{% extends "foo/bar"|add_html_extension %}

And the filter will be applied to "foo/bar" before the call to extends. I figured this would work with the include tag as well, but it doesn't.

{% include "foo/bar"|add_html_extension %}

Here, the filter will never be called. Could we fix this?

[Johannes Dollinger]

This would be fixed by the refactoring proposed in #7806.

[Malcolm Tredinnick]

No, this really isn't worth it. It's "programming in templates". Just pass in the right value to include (in a variable).
