[WIP/PATCH 0/5] git checkout --recurse-submodules

[Jonathan Nieder <jrnieder@gmail.com>]

Hi,

This patch series comes from
https://github.com/jlehmann/git-submod-enhancements branch
recursive_submodule_checkout.  It needed some tiny tweaks to apply to
current "master" and build without warnings, but nothing major, and I
haven't sanity checked it much beyond that and letting the kind folks
that use Debian experimental play with it.

I'm sending it out now to get review and ideas for what needs to
happen next to get this series in shape to be included in git.git.

Thoughts of all kinds welcome.

Thanks,
Jonathan
