I am not sure what problem you are trying to solve here. I installed
stgit here on my ubuntu system. It pickes git from my Ubuntu installation.

stgit contains a generic program launcher in "stgit/stgit/run.py":

class Run(object):
    exc = RunException
    def __init__(self, *cmd):
        self.__cmd = list(cmd)

The first entry in self.__cmd is the executable. I could replace
self.__cmd[0] with the full path to git when self.__cmd[0] == "git".
But I don't know why this is useful/needed.

Could you try to explain what you want to achieve?

Two of the tests are failing. But I don't see why they fail. I disabled
them to make the test phase succeed.

I have attached the current version of my patch.

> Thanks in advance!
