Hi git,

I cloned git mirror from github[1]. When I run git-status in it's working directory, I see no output.

But then, after copying the whole directory with 'cp -r' and running git-status in the newly created directory, I get the following:

Show 6 quoted lines

> # On branch master
> # Changed but not updated:
> #   (use "git add <file>..." to update what will be committed)
> #   (use "git checkout -- <file>..." to discard changes in working directory)
> #
> #	typechange: RelNotes

git-diff shows

Show 6 quoted lines

> diff --git a/RelNotes b/RelNotes
> new file mode 100644
> index 0000000..56c3863
> --- /dev/null
> +++ b/RelNotes
> ... // the whole contents of the file

Both copies of the repository are on the branch master with the latest commit 07873dc. Simply diffing copies of the RelNotes file gives no output.

What happened with the copied repository? I've found a couple of instances of the word 'typechange' in the source, but no mention in the docs. What does it mean and what could be the cause of this change?
