Subject: git submodule add --single-branch
Message-ID: <8e46e2f93895fb33421e7b09ccfe7de5@www.hilie.de>

I would like to do a shallow clone of a submodule like this:
$ git submodule add --branch master --single-branch --depth 5 repo dir
but it doesn't work. I think '--single-branch' is not yet implemented 
for submodules.

With the clone command it works:
$ git clone --branch master --single-branch --depth 5 repo dir

Is it possible to do something like this with a submodule?
