This is a brown paper bag. When adding the tests, we actually failed
to verify that the config variable is heeded in git-init at all. And
when changing the original patch that marked the .git/ directory as
hidden after reading the config, it was lost on this developer that
the new code would use the hide_dotfiles variable before the config
was read.

The fix is obvious: read the (limited, pre-init) config *before*
creating the .git/ directory.

This fixes https://github.com/git-for-windows/git/issues/789

OK.  I think this is very much futureproof and a sensible thing to
have a "platform_core_config()" call here.  That way, we do not have
to say the details of what platform specific thing each platform
wants when init_db_config works.

And from that point of view, replacing `core.hidedotfiles` with
something like "platform specific core config" would be more
appropriate.

We use git_init_db_config from create_default_files(), which is a
function called several lines after this point; shouldn't that now
be removed from create_default_files()?

This is not incorrect per-se, but I think most tests do the mkdir
outside subshell, i.e.

	rm -rf newdir &&
	mkdir newdir &&
	(
		cd newdir &&
		sane_unset ... &&
		...
	) &&

Other than these, I find nothing questionable in the patch.  Nicely
done.

I am glad you agree.

Probably. But it could potentially make some developer (such as myself,
six months from now) wonder why we don't just remove this call because
clearly nothing uses this on Linux.

So even if it is not quite future-proof from the point of view where we
*technically* would have to extend this comment if we ever introduced
another platform-specific config setting that is relevant to the early
phase of `git init`, I would like to keep the comment in the current form.

Well, actually *almost* in the current form.

I did realize, based on your comment below, that the mention of
`init.templatedir` here is bogus, wrong even: if `git init` is started in
a Git worktree, we do not *want* to use the `init.templatedir` setting
from said worktree.

And that is the reason why...

... we have to call `git_config()` *again* in `create_default_files()`.

This fixes an regression that was not present in Git for Windows's original 
core.hideDotFiles patch, but in the shape of the core.hideDotFiles patch
that made it into git.git.

We fixed it in one big hurry in Git for Windows, and I simply forgot to
upstream this right away.

Changes since v1:

 * Clarified in the code comment that our intention is to pick up 
   core.hidedotfiles in the first git_config() call.
 * Explained in the commit message why we cannot remove the 
   git_config(git_init_db_config, NULL) call from create_default_files(): it
   would cause a change of behavior with regard to the init.templatedir 
   setting.
 * Simplified the test case.
