tests: prevent Git system and global configuration from loading
This reduces differences between different testing environments. Something
similar is already done for Mercurial (in the lines directly above this
change).
Yes, I agree that it is a problem/bug that the global configuration is
used at all. Global configuration should be disabled for git, as we do
for hg.
The parent changeset has originally been added to support user.useconfigonly.
With this changeset, the original motivation for it becomes obsolete. However,
it is still necessary to set the committer name via a environment variable, at
least on my machine.
I think this changeset should come first. As you say, it makes the test
work the same way everywhere. user.useconfigonly is probably just one of
many settings that could break it.
If it still doesn't work for you with this change (without the previous
change), it can't be because your setup has user.useconfigonly set.
There must be some other explanation.
(Note that the GIT_CONFIG_ environment variables were introduced two
years ago, and Kallithea still supports the 10 year old Git 1.7.4 . We
must thus make sure we don't rely too much on the new feature.)

As mentioned before: the git man page is very clear that the variables
should be set to /dev/null to skip reading configuration files.
There is no indication in the git man page (or anywhere else I have
found) that setting to /dev/null shouldn't work across all platforms. It
seems like git in compat/mingw.c takes care of making it cross platform.
There is no mention of the semantics of setting it to an empty string. I
do not like relying on undefined behaviour.
If you disagree and have found a good reason to use an empty string
instead of /dev/null, then please be explicit in code or commit message.
