Changeset 48961 for trunk/src/wp-includes/comment.php

Message:

Code Modernization: Remove unnecessary reference sign from get_comment() definition.

This fixes a PHP 8 "argument must be passed by reference, value given" error when using array_map( 'get_comment', ... ).

Object variables in PHP 5+ contain a reference to the object, and it's the reference that's passed around.

Note: This reverts [48838], which is now redundant.

Follow-up to a similar change for get_post() in [21572].

See #50913.
