Protect multi-line macros expansions in _test*.c files #120674
Description
Feature or enhancement
Proposal:
In Modules/_testbuffer.c and Modules/_testcapimodule.c, there are some expansions that are not protected, although their usage is correct.
This issue is in continuation with #119981 (comment) and #120017. There are other places where macro expansions are not protected, so I'll work on that when I've some free time (those PRs are quite easy to review and to implement IMO).
Has this already been discussed elsewhere?
