Comment (by SergeyBiryukov):

 In [changeset:"48961" 48961]:
 {{{
 #!CommitTicketReference repository="" revision="48961"
 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.
