Re: [PATCH v2 4/4] cat-file: add mailmap support

+char *replace_idents_using_mailmap(char *object_buf, size_t *size)

Does this function need to be extern?  If nobody other than callers
in cat-file would call it, perhaps it should be file-scope static.

+{
+	struct strbuf sb = STRBUF_INIT;
+	strbuf_attach(&sb, object_buf, *size, *size + 1);
+	const char *headers[] = { "author ", "committer ", "tagger ", NULL };

This is decl-after-statement.

+	apply_mailmap_to_header(&sb, headers, &mailmap);
+	*size = sb.len;
+	return strbuf_detach(&sb, NULL);
+}
