[PATCH] Fix premature call to git_config() causing t1020-subdirectory to fail

[Johan Herland <johan@herland.net>]

We need to call git_config(git_default_config) in order to get user.name and
user.email (so that reflogs will be correct), but if we do it too early, it
interferes with the setup of reference repos. Therefore, move git_config()
call to _after_ the reference has been setup (but before we start writing
reflogs). However, in order for git_config() to read in the global
configuration at that point, we must unset CONFIG_ENVIRONMENT.

There are probably better ways of resolving this issue.

Here is a fix for this breakage, although I think it's ugly as hell.

But with this fix, and the other one I just sent out for the
for_each_ref() corruption, the whole test suite finally passes on my
box.

Feel free to incorporate this into the further builtin-clone work,
or ignore it, and find better ways of solving these issues.


Have fun! :)
