#39535: Canonical redirects disallow tag named comments

--------------------------+-----------------------------
 The `redirect_canonical` function includes a regular expression
 replacement which effectively disallows tags named "comments" to have an
 RSS feed:

 https://github.com/WordPress/WordPress/blob/master/wp-
 includes/canonical.php#L285

 For example:

 /blog1/tag/comments/feed/

 This is redirected to:

 /blog1/tag/feed/

 Could / should the regular expression on line 285 could pay attention to
 the first placeholder it matched (`comments/?`) or check whether the page
 is a tag request?
