Hi!

(Please don't hesitate to submit bug fixes upstream, especially 
when the breakage is so clearly unintentional :-)

I changed the changelog to better follow our standards

    gnu: grep: Fix PCRE matches (grep -P).

    {{{No blurb here if it only rephrases the title.}}}

    * gnu/packages/base.scm (grep)[inputs]: Replace pcre with 
    pcre2.
    [arguments]: Add "--enable-perl-regexp" to #:configure-flags 
    to
    detect broken PCRE in future.

and pushed this to core-updates as 
5b0cea02358044f0cc695bacc3f44db1e220239b.

Thanks,

T G-R
