Noindex unapproved comment previews.

[peterwilsoncc]

Adds a noindex directive to pages showing a preview of an unapproved comment prior to moderation.

Although the pages have a canonical URL referring to page without the comment preview has, the URL can be indexed by search engines none-the-less. I presume this is due to the content differing.

LGTM, thanks @peterwilsoncc !

Thanks @peterwilsoncc, LGTM!

@felixarntz @jdevalk I realized overnight that the filter I used doesn't include the noarchive directive, should I use wp_robots_sensitive_page() instead?

@felixarntz @jdevalk I realized overnight that the filter I used doesn't include the noarchive directive, should I use wp_robots_sensitive_page() instead?

I'm not sure. The change here is not really about a "sensitive page" I would argue, and when looking at other usages of wp_robots_no_robots() and wp_robots_sensitive_page(), the first seems to be more in line with what's needed here. But to be fair, I'm also unsure whether or not the noarchive needs to be set here.

[jdevalk]

I’m ok with either

[peterwilsoncc]

Thanks both, I'll go with the existing code to avoid complexity.
