Makes sense.

This could be "const char *hash", couldn't it?

Returning "-1" for error is more idiomatic in our code base (though I
know some of the commit-graph code doesn't follow that, I think we
should slowly try to move it back in the other direction.

This leaks "line" for each commit in stdin_commits mode (it used to get
added to a string list). I think you want:
while (strbuf_getline(&buf, stdin) != EOF) {
if (opts.stdin_commits) {
if (read_one_commit(&commits, buf.buf)) {
strbuf_release(&buf);
return 1;
}
} else {
string_list_append(&pack_indexes, strbuf_detach(&buf));
}
}
Though I think it might be easier to follow if each mode simply has its
own while loop.

Not new in your patch, but this UNLEAK() has always bugged me. ;) Why
not just strbuf_release() it?
