  I'm not sure you need the ETA thing. I've used bzr only a couple of
time, I don't think it shows any kind of ETA, but I think I remember sth
like:

Stage 3/4
[==========================>                                    ] [43%]

  And that's all is needed. It's sober, and informative enough I think.


  Many git commands output are still messy and indeed, having them in C
should help in that regard. The usual culprit are I think:

  * git fetch/clone/pull/.. ;
  * git push ;
  * git repack/gc/... ;
  * git merge (even with the merge.verbosity set to the minimum it's
    still not very readable and confusing).


  I do believe that the quite verbose output git commands sometimes have
is quite confusing, and let the user think it's messy. I believe that
porcelains should be more silent, it's OK for the plumbing to spit
progress messages and so on, because people using the plumbing are able
to understand those, but porcelains should not.
