I see even more promising results from a single run on one of my Cygwin
systems: from 21.3 seconds for t3070 to 0.112 seconds for your t3071.  I
expect there's a similar improvement in Dscho's Git for Windows
environment.

I don't follow: if we end up implementing every test twice, as we have
here, then I agree, but I don't think there's much value in doing that
except as a proof of concept, as in this immediate discussion.  The
obvious-to-me way to do this would be following the precedent of the
core code: gradually migrate things away from shell code to C code.
