Yes, I have that annoyance, and I usually want to debug one very specific Git call in that script. Therefore, I made this patch:
https://github.com/git-for-windows/git/commit/0f50fd723beb5d27d2d799ef3a0cfc0b0bbd80a8
It really served me well during the past four months of Git for Windows 2.x work. Of course I also had to avoid the redirection:
https://github.com/git-for-windows/git/commit/d27cb6e0572475582677724545a71755d171ea76
So what I do these days is to run the failing test with `TEST_NO_REDIRECT=1` and with the Git call I want to debug prefixed with `TEST_GDB_GIT=1`.

Ciao, Dscho
