Some git mv questions

Hi,

For the impatient, start [HERE].

I'm about to start shuffling files and directories around in a big project, while others keep working on their files. This is a bit scary as I still feel pretty much newbie in the GIT world :-)

I did a little test as follows. Given a shared repository sandbox.git with a file in there I did the following, which worked fine.

	* [player one] clone the DB, edit the file, commit and push
	* [player two] clone the DB
		- git branch shuffle
		- git checkout shuffle
		- mkdir SomeDir
		- git mv file SomeDir
		- edit SomeDir/file
		- git commit -a
	* Sofar so good, now merge:
		- git checkout master
		- git pull (get player 1 changes)
		- git merge shuffle
		- git branch -d shuffle
		- git commit -a
		- git push

Sofar so good, but during the tests I had two times problems:

	* Instead of "git mv file SomeDir" I simply used "mv file SomeDir"
	and git-add.  Now I end up with two files and of course the changes
	are not merged.  I can understand that.

[HERE]
	* On a somewhat bigger test I moved a large directory using
	"git mv dir newdir" (where newdir is an existing directory).
	Now "git status" gives a lot of new and deleted files!?  I
	guess I'm going to have a big mess if that happens in the
	real project.  Moving some smaller test directories simply
	showed a series of renames.

	Can this be explained?  Is this a bug?

	Thanks --- Jan
