Hi Junio,

Sorry for the spam but it seems like this patch was dropped. If there
aren't any other comments on the patch, then I think it's ready to be
queued. Patch below for your convenience.

Thanks,

Subject: [PATCH] contrib/subtree: ensure only one rev is provided

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 change "<commit...>" to "<commit>" to reflect this. In addition,
check the arguments to ensure that only one rev is provided for all
subcommands that accept a commit.
