Other than Brandon's issue on 3/5 (which I noticed myself but wanted to 
double-check that my mailer wasn't playing tricks on me and so lost the race to 
report), this version looks good.

> Subject: [PATCHv4 0/5] git-rm absorbs submodule git directory before
> deletion
> 
> v4:
> * reworded commit messages of the last 2 patches
> * introduced a new patch introducing {run,start,finish}_command_or_die
> * found an existing function in dir.h to use to remove a directory
>   which deals gracefully with the cornercases, that Junio pointed out.
> 
> v3:
> * removed the patch to enhance ok_to_remove_submodule to absorb the
> submodule
>   if needed
> * Removed all the error reporting from git-rm that was related to
> submodule
>   git directories not absorbed.
> * instead just absorb the git repositories or let the absorb function die
>   with an appropriate error message.
> 
> v2:
> * new base where to apply the patch:
>   sb/submodule-embed-gitdir merged with sb/t3600-cleanup.
