URL for 1st comments page is not canonical

[sirzooro]

When WP generates URL for comments, it always includes comments page number. It should not do this when URL is for 1st comments page - in this case post URL is sufficient.

WP should also redirect to canonical URL version when someone will try to load URL like site.com/some-post/comment-page-1.

Punting to Future Release pending patch.

Any chance for a patch? Any feedback from GSOC which is over now?

This report properly is not valid. If there is a theme that seperates comments on a page "on it's own" next to the page "that is post content", then this information is needed.

Probably that sort of canonicalization is something a theme need to take care of.

Can this be revisited?

/comment-page-1 is extraneous and bad for SEO due to duplicate content for situations where the total number of comments is < 1 page (new replies are automatically redirected to /comment-page-1 instead of the canonical url).

For the case when the total number of comments is > the per-page one, either comment-page-1 or comment-page-LASTNUM is superfluous, depending on the sort order.
