While tring to get to grips with some Git-for-Windows config settings
for testing >4GiB files, I couldn't find any note in the readme about
the test system config file sources.
The path of the system config file is determined at compile time, with
no way to override it at runtime.  Since we don't want external config
files influencing our tests, the only choice we have is to ignore the
system config file; that's why our test framework sets
GIT_CONFIG_NOSYSTEM=1.
Thanks.
Is this the right place for the information, is it complete enough,
and is the default config template special?

However, note that the global config file isn't really ignored, but
different.  The path of the global config file depends on the values
of the env variables $XDG_CONFIG_HOME and $HOME, and, again, to avoid
external influences, our test framework unsets the former, and
overrides the latter with HOME="$TRASH_DIRECTORY".  IOW the global
config file in our tests is '.../t/trash directory.t1234-foo/.gitconfig'.

I'll revise the text with this clarifying information (rephrased to man page style)
