[PATCH v2 0/1] Fix git init with core.hidedotfiles




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.

  mingw: respect core.hidedotfiles = false in git-init again

          The fix is obvious: read the (limited, pre-init) config *before*
          creating the .git/ directory.
      
     +    Please note that we cannot remove the identical-looking `git_config()`
     +    call from `create_default_files()`: we create the `.git/` directory

     +    `init.templatedir` setting, we would all of a sudden pick that up.
