git checkout: do not allow switching to a tree-ish that is not a commit
"git checkout -b newbranch $commit^{tree}" mistakenly created a new branch rooted at the current HEAD, because in that case, the two structure fields used to see if the command was invoked without any argument (hence it needs to default to checking out the HEAD) were populated incorrectly. Upon seeing a command line argument that we took as a rev, we should store that string in new.name, even if that does not name a commit. This will correctly trigger the existing safety logic.
