The first one does fix a possible stack overflow (albeit of one NULL,
not arbitrary content, so I don't think it's exploitable). We may want
to do:
diff --git a/diff.c b/diff.c
index 54d5308..a03744b 100644
--- a/diff.c
+++ b/diff.c

const char **arg = &spawn_arg[0];
struct diff_queue_struct *q = &diff_queued_diff;
as a fix for maint/2.0.0 in the interim. I can write a commit message
for that if you're interested.

If you are waiting on me, I do not have much else to say on this topic.
@{publish} as specified by Felipe is not useful to me, and I would
continue to pursue @{push} separately as "the remote-tracking branch of
where you would push to". I think there is room for both concepts.
As for the patches themselves, I have not reviewed them carefully, and
would prefer not to. As I mentioned before, though, I would prefer the
short "@{p}" not be taken for @{publish} until it has proven itself.
