Include directives with target containing spaces not working with -S secure

[dometto]

The following syntax:

include::foo bar.adoc[]

• works as intended with -S unsafe
• outputs the following with -S secure: link:foo bar.adoc[role=include]

It looks like:

1. it's converting the include directive to a link directive because of secure mode (intended)
2. but this link directive is not being rendered because of the space

Since it's intended functionality that asciidoctor supports include directives with targets including spaces, this seems like a bug to me. If targets including spaces are supported, and include directives with -S secure are too, shouldn't include targets with a space in secure mode also be fully supported?

I think the intuitive behavior would be for the link in secure mode to be rendered as follows: <a href="foo%20bar.adoc" class="bare include">foo bar.adoc</a>
