[PATCH/RFC RESEND 0/2] git subtree: an alternative to git submodule

Hi all,

I first sent out this patch set a couple of weeks ago (http://article.gmane.org/gmane.comp.version-control.git/117612) and got a couple of positive comments, but no negative ones, so I'm guessing people haven't reviewed it as closely as I would have hoped :)

git subtree has these subcommands:

 - add: connect a given commit to a given subtree, basically using the
   occasionally-documented 'git read-tree --prefix; git commit' trick.

 - merge: a user-friendlier form of 'git merge -s subtree'

 - pull: likewise, but for git pull

 - split: (the magical part!) generate a new commit series from the given
   prefix, so you can submit subtree changes *back* to the upstream project
   you merged in the first place. 

Does anyone have any comments on what it would take to get the git subtree stuff accepted into git?

Thanks,

Avery
