grep/pcre2: prepare to add debugging to pcre2_malloc()

avar · gitster · commit 588e4fb19190 · 2021-02-17T16:32:19.000-08:00
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 513f2b0 (grep: make PCRE2 aware of custom allocator, 2019-10-16).
