t9101 did not fail for me before your patches.  However I have a
patch on top of your 2/2 which should fix things.

`git rev-parse --show-cdup` outputs nothing if GIT_DIR is set,
so I unset GIT_DIR temporarily.

I'm not sure why --show-cdup behaves like this, though..

Does squashing this on top of your changes fix all your failures?
I plan on squashing both your changes together with the below:

diff --git a/git-svn.perl b/git-svn.perl
index c232798..e5bd292 100755
