I guess this is largely my fault, but I think "git grep" is an
easier source of truth to work with than the list archive.
It eventually boils down to branch.*.description configuration and
all users of that would call read_branch_desc(), so if you check
callers of that helper function and see which commit introduced that
call for what purpose ("blame" is your friend), you would know how
they use the information under what condition.
$ git grep -n read_branch_desc -- \*.c
branch.c:143:int read_branch_desc(struct strbuf *buf, const char *branch_name)
builtin/branch.c:771: read_branch_desc(&buf, branch_name);
builtin/fmt-merge-msg.c:211: if (!read_branch_desc(&desc, name)) {
builtin/log.c:888: read_branch_desc(&desc, branch_name);
$ git blame -L210,212 -s builtin/fmt-merge-msg.c
898eacd8 210)
898eacd8 211) if (!read_branch_desc(&desc, name)) {
898eacd8 212) const char *bp = desc.buf;
$ git show -s 898eacd8

fmt-merge-msg: use branch.$name.description
This teaches "merge --log" and fmt-merge-msg to use branch description
information when merging a local topic branch into the mainline. The
description goes between the branch name label and the list of commit
titles.
The refactoring to share the common configuration parsing between
merge and fmt-merge-msg needs to be made into a separate patch.
