[Bro-Dev] "git diff" questions

[Vern Paxson]

On a checkout for which I haven't touched aux/broccoli, if I issue "git diff"
it tells me:

	diff --git a/aux/broccoli b/aux/broccoli
	index 9866a00..8843da5 160000
	--- a/aux/broccoli
	+++ b/aux/broccoli
	@@ -1 +1 @@
	-Subproject commit 9866a00e78b088315e632960aaa230635bca326a
	+Subproject commit 8843da57dc8aee433550727dcbd1199824ca9da4

(1)  Why is it finding a difference?  (2) How do I get it to show me
what the difference actually is?
