Here is 2 pcretest listings:


1.
PCRE2 version 10.35 2020-05-09

/a\K.(?0)*/
abac
0: bac


Expected result: c
Perl's result: c



2.
/a\Kb/replace=-$0-
ab
1: a-b-


PCRE doc's says about $<n> substitutions:
"The number may be zero to include the entire matched string."

But really we can see that entire matched string "ab" is not included in
substitution.
So there is need to change either doc's or pcre2_substitute() behaviour
