Re: [O] Bash script to update - only make when update there?

This doesn't update at all since you never do a "git pull" on master.

I really don't see why you'd need to use a shell script for that
(instead of adding your own target in local.mk), but that aside you'd
want to compare the SHA1 of your checkout with the SHA1 of your last
install (for instancefrom org-version.el).  If there wasn't an update
these two would be identical.
