I really like where this is heading!

Some minor issues:

- I think we should be more verbose in the commit message,
  including that and why the default should be "on". Maybe
  like this?

  "Permit to do a 'git clone --recursive' through git-gui.
  Add a 'recursive' checkbox in the clone menu which allows
  users to clone a repository and all its submodules in one
  go (unless the 'update' flag is set to "none" in the
  .gitmodules file for a submodule, in that case that
  specific submodule is not cloned automatically).

  Enable this new option per default, as most users want to
  clone all submodules too when cloning the superproject
  (This is currently not possible without leaving git gui
  or adding a custom tool entry for that)."


- I'd rather change the button text from "Recursive (For
  submodules)" to something like "Recursively clone
  submodules too" or such.


- Wouldn't it be easier to pass the '--recurse-submodules"
  option to the "git clone" call for the superproject instead
  of adding the _do_clone_submodules() function doing a
  subsequent "git submodule update --init --recursive"? That
  is also be more future proof with respect to the autoclone
  config option we have in mind (which would add that behavior
  for "git clone" itself, making the call you added redundant).
