While looking at the inline help for git-subtree.sh, I noticed that git subtree split --prefix=<prefix> <commit...> was given as an option. However, it only really makes sense to provide one revision because of the way the commits are forwarded to rev-parse so this commit changes "<commit...>" to "<commit>" to reflect this. In addition, it checks the arguments to ensure that only one rev is provided for all subcommands that accept a commit.
