[BUG] inconsistent behavior with --set-upstream vs --set-upstream-to

Hi!
	It looks like git branch --set-upstream-to doesn't function with 1.8.1.3 until I run --set-upstream. Is this a known bug?

root@fuji-current:/usr/src # git branch --set-upstream-to origin/pjdfstest-onefs pjdfstest-onefs fatal: Not a valid object name: 'origin/pjdfstest-onefs'. root@fuji-current:/usr/src # git branch --set-upstream origin/pjdfstest-onefs pjdfstest-onefs The --set-upstream flag is deprecated and will be removed. Consider using --track or --set-upstream-to Branch origin/pjdfstest-onefs set up to track local branch pjdfstest-onefs. root@fuji-current:/usr/src # git branch --set-upstream-to origin/pjdfstest-onefs pjdfstest-onefs Branch pjdfstest-onefs set up to track local branch origin/pjdfstest-onefs. root@fuji-current:/usr/src # git --version git version 1.8.1.3

Thanks! -Garrett
