Gscan complains about correct usage of {{author}} in context of default.hbs

[adamkudrna]

This is the logic of my theme's page title in default.hbs which actually works:

    <title>
        {{#is "home"}}
            {{@site.title}} — {{@site.description}}
        {{/is}}
        {{#is "author"}}
            {{author.name}} | {{@site.title}}
        {{/is}}
        {{#is "tag"}}
            {{tag.name}} | {{@site.title}}
        {{/is}}
        {{^is "home, author, tag"}}
            {{meta_title}} | {{@site.title}}
        {{/is}}
    </title>

However, when I run gcan (the latest version, 3.6.0), it throws an error saying:

Checking theme compatibility...

Your theme has 1 error!
----

Errors
------
Important to fix, functionality may be degraded.

- Error: Replace the {{author.name}} helper with {{primary_author.name}} or {{authors.[#].name}}
Files: default.hbs

I think this is a false alarm which should be fixed (I wish I could do it).

This issue is a good example of why migrating to AST-based rules for author-related errors like done here is a good idea.
