[PATCH 1/3] Fix potential command line overflow in hooks--update

In a repository with a large number of refs, the following command line
could easily overflow the command line size limitations

 git-rev-list $newref $(git-rev-parse --not --all)

Fortunately, git-rev-list already has the means to cope with this
situation with the --stdin switch

 git-rev-parse --not --all | git-rev-list --stdin $newref

Which is exactly what this patch does.
