Comments - no custom columns hook

[stencil]

There is a do_action('manage_comments_custom_column') in:
wp-admin/includes/class-wp-comments-list-table.php (Line 503)

But no hook to filter the columns of the Comments table.

Small possible fix attached which applies filter.

You can use the 'manage_edit-comments_columns' filter.

Here are the filters for all the screens:

Ah, thanks for that resource.

I couldn't find anything in the Codex, and searching the source was failing due to using the full string "manage_edit-comments_columns".
