  $ git config --global init.defaultBranch master

  $ hg version -v --config extensions.git= | grep '^[E ]'

  Enabled extensions:

    git  internal  (pygit2 *) (glob)

Test auto-loading extension works:

  $ mkdir nogit

  $ cd nogit

  $ mkdir .hg

  $ echo git >> .hg/requires

  $ hg status

  abort: repository specified git format in .hg/requires but has no .git directory

  [255]

  $ git config --global init.defaultBranch master

  $ git init

  Initialized empty Git repository in $TESTTMP/nogit/.git/

This status invocation shows some hg gunk because we didn't use

`hg init --git`, which fixes up .git/info/exclude for us.

  $ hg status

  ? .hg/cache/git-commits.sqlite

  ? .hg/cache/git-commits.sqlite-shm

  ? .hg/cache/git-commits.sqlite-wal

  ? .hg/requires

  $ cd ..

Now globally enable extension for the rest of the test:

  $ cat <<EOF >> $HGRCPATH

  > [extensions]

  > git=

  > [git]

  > log-index-cache-miss = yes

  > EOF

Test some edge cases around a commitless repo first

  $ cd empty

  $ git init

  $ cd ..

Make a new repo with git:

  $ mkdir foo

  $ cd foo

  $ git init

  Initialized empty Git repository in $TESTTMP/foo/.git/

Ignore the .hg directory within git:

  $ echo .hg >> .git/info/exclude

  $ echo alpha > alpha

  $ git add alpha

  $ gitcommit -am 'Add alpha'

  $ echo beta > beta

  $ git add beta

  $ gitcommit -am 'Add beta'

  $ echo gamma > gamma

  $ git status

  On branch master

  Untracked files:

    (use "git add <file>..." to include in what will be committed)

   (?)

  	gamma

  nothing added to commit but untracked files present (use "git add" to track)

Without creating the .hg, hg status fails:

  $ hg status

  abort: no repository found in '$TESTTMP/foo' (.hg not found)

  [10]

But if you run hg init --git, it works:

  $ hg init --git

  $ hg id --traceback

  $ hg bookmarks

  $ hg bookmarks

   * master                    1:3d9be8deba43

diff even works transparently in both systems:

  $ echo blah >> alpha

  $ git diff

  diff --git a/alpha b/alpha

Remove a file, it shows as such:

Revert works:
