I couldn't find a way to get `arc diff` to ignore these, as they appeared to git to be a change in a tracked file (that is, a change to a submodule, which is considered tracked). `git stash` offered no help, so I had to delete the untracked files. This didn't cause real pain (the files were there in error), but it seems a weakness of the system if I can't make progress otherwise.

If you go into your .git/config file in the GHC repo, and add "ignore = 
untracked", like this:

[submodule "nofib"]
	url = /home/simon/ghc-mirror/nofib.git
         ignore = untracked

Then git won't consider untracked files in that submodule as making that 
submodule dirty, and you'll be able to happily "arc diff".
