They are equivalent, except that "..." in

	git checkout --detach A...B


is internal as opposed to

	git checkout --detach $(merge-base A B)

that uses one extra process.  I thought people loath spawning
processes?

It will make it easy for you to look at 

	git log --first-parent --oneline master..

by hiding the base commits you depend on behind a single merge
commit.

Again this is to help that "one liner first-parent chain" output.
