I agree with Junio "git-all" is too generic. Maybe "git-for-each-repo"

Perhaps we could add the subrepo's object data to the in-memory object
database of git-all, then do the diff without launching new commands?

I'm not a user of this command so this is more of bikeshedding. I
think we should have an option to list repos listed in index. For
directory walk, how about reusing fill_directory() to do the job for
you? You could then limit repositories by name. "ls-files -o" code
should be very similar.
