bug#60621: Duplicate 0f #60618

Hi I first filed the original issue for pcre2grep after a Twitter discussion, and then also sent it to the bug-grep list, but Carlo Arenas had already noticed it (but it had not been registered from what I could see), so it is a duplicate of #60618. -- Karl Pettersson Uppsala, Sverige/Sweden
