The patch actually does this in the --stdout case. Look at the last
hunk in builtin/pack-objects.c:
@@ -2349,6 +2366,9 @@ int cmd_pack_objects(int argc, const char **argv, const char *prefix)
if (non_empty && !nr_result)
return 0;
+ if (pack_to_stdout && object_count_limit && object_count_limit < nr_result)
+ die("unable to make pack within the object count limit"
+ " (%lu objects)", object_count_limit);
if (nr_result)
prepare_pack(window, depth);
write_pack_file();
So in the --stdout case, we have already aborted before we start
writing the pack (i.e. after the counting phase).
The commit message you quote above, are for the case where someone uses
--max-object-count _without_ --stdout, in which case we compare
nr_written to object_count_limit to determine when to split the pack.
