Don't do this.

If the merge just fast-forwarded, you'll do the wrong thing.

So yes, it _works_, but it only works if you actually ended up having a 
real merge. In contrast, the ORIG_HEAD thing always works.

ORIG_HEAD is also particularly useful for doing things like "ok, what did 
I get from that pull?" especially when you track somebody elses work (in 
which case it will basically _always_ be a fast-forward). So I do

	gitk ORIG_HEAD..

in git almost every time I pull from Junio's git thing, just because it's 
a wonderful way to see what has changed, if you're interested in that kind 
of detail.
