Comment (by SergeyBiryukov):

 In [changeset:"49186" 49186]:
 {{{
 #!CommitTicketReference repository="" revision="49186"
 Code Modernization: Remove unnecessary reference sign from
 `PO::export_entry()` definition.

 This fixes a PHP 8 "argument must be passed by reference, value given"
 error when using `array_map()` in `PO::export_entries()`.

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

 Props jrf.
 See #50913.
