[PATCH 00/10] teach --progress to transport-related builtins

This patch series adds --progress to:

  - git-fetch
  - git-pull
  - git-push

I suspect the most contentious issue in this patch series would be the logic that determines whether progress reporting is done. This is found in patch 6 for transport.c::transport_set_verbosity().

As a guide, I used Jeff's message (gmane#121065). The rules used are as follows (processing aborts when a rule is satisfied):

  1. Report progress, if force_progress is 1 (ie. --progress).
  2. Don't report progress, if verbosity < 0 (ie. -q/--quiet).
  3. Report progress if isatty(2) is 1.

This changes the current implementation such that if both --progress and --quiet are specified, progress is reported. I don't think this is a very significant change, but I think it makes sense, since I expect --progress to be mostly used by script writers or IDE integrators (to force progress reporting even if stderr is not a terminal).
