[Cogito] less verbose cg-clone/cg-update?

Hi there,

as a person just following the development process of Linux/GIT/etc. I'm normally not interested in SHA-1 sums on updating my local tree. IMHO the default output should be less verbose (like in most VCSs), especially in file changes the type of change (N/M/...) and the file name may be enough. Given an option (e.g. "-v") there could be a lot more...

If there's no time, I'd do the patch...

P.S.: I didn't really look at the source, maybe it's a git not
      a cg-* change...
