Hmm.  My initial feeling is that if your pre-commit hook doesn't want
you to commit, we should respect that.  Although I'm not sure how to
handle this case for folks like you that don't define a global
username or email address.  Possibilities:

* Drop the empty commit from ‘nmbug init’ and teach ‘nmbug log’,
  ‘status’, ‘commit’, etc. to handle the “we don't have any commits
  yet” case?  That gives you time between the init and first commit to
  go into the repository and setup your username and email address by
  hand.  This would be the most work, but gives us a more native
  solution (‘nmbug init’ maps more directly to ‘git init’).

* Adjust the syntax to:

    nmbug init -- {arguments passed through to ‘git commit’}

  so you could run:

    nmbug init -- --author 'A U Thor <author at example.com>'

  or:

    nmbug init -- --no-verify

  this works as long as the tweak you need is accessible from a ‘git
  commit’ argument (I guess --no-verify covers us there).

From the template pre-commit.sample:

  The hook should exit with non-zero status after issuing an
  appropriate message if it wants to stop the commit.

so you should check that your hook is doing that if you expect to
abort commits it doesn't like ;).

Good point.  I've added:

  if _os.path.exists(NMBGIT):
      raise ValueError('NMBGIT path ({!r}) already exists'.format(NMBGIT))

for v5.

Cheers,
Trevor
