I don't personally feel that the existing progress bar is that bad, but
if anybody wants to pursue this, I think the most sensible path is:

  1. Add a trace_key for sending machine-readable progress output to a
     descriptor or file. E.g., via setting GIT_TRACE_PROGRESS=2 in the
     environment.

  2. Teach the trace code to open a command for piping, so that you
     could do something like GIT_TRACE_PROGRESS='|mygauge'.

That would make your use case work, and I think many other use cases
would benefit from both of those features independently.
