Thanks for the answers :)

After seeing that git push skips the packing (and potentially other
things) when doing a dry run, and given that:
	git push --dry-run
takes 1.5s on average and that:
	git fetch
	git rev-list master..remotes/origin/master
OR
	git ls-remote origin refs/remotes/origin/master

take 4s on average, I think I'll stick with the dry-run & checking for
exception method.

Thanks though :)
