Subject: [PATCH 05/25] grep/pcre2: prepare to add debugging to pcre2_malloc()

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Wed, 3 Feb 2021 04:27:51 +0100

Change pcre2_malloc() in a way that'll make it easier for a debugging
fprintf() to spew out the allocated pointer. This doesn't introduce
any functional change, it just makes a subsequent commit's diff easier
to read. Changes code added in 513f2b0bbd4 (grep: make PCRE2 aware of
custom allocator, 2019-10-16).
