Hi,

I am trying to add a submodule with option --branch and --depth 
together, and failed. However, there is no problem if only one of them 
is applied.

So, this worked:
git submodule add --branch develop 
https://anton@bitbucket.org/anton/mysubmodule.git

This is also worked:
git submodule add --depth 1 
https://anton@bitbucket.org/anton/mysubmodule.git

But this won't worked:
git submodule add --branch develop --depth 1 
https://anton@bitbucket.org/anton/mysubmodule.git


Here is how to replicate the problem:

Setup remote repositories, e.g. in bitbucket:
For superproject: https://anton@bitbucket.org/anton/mysuperproject.git
For submodule: https://anton@bitbucket.org/anton/mysubmodule.git

Setup local repository for superproject:
git init mysuperproject
cd mysuperproject
echo "This is the parent project" > README
git add README
git commit -m "add README"
git remote add origin https://anton@bitbucket.org/anton/mysuperproject.git
git push --all -u origin

Setup local repository for submodule with branch "develop":
cd ..
git init mysubmodule
cd mysubmodule
echo "This is the submodule" > README
git add README
git commit -m "add README"
git branch develop master
git remote add origin https://anton@bitbucket.org/anton/mysubmodule.git
git push --all -u origin

Now, go to superproject and add submodule with options --branch and --depth:
cd ../mysuperproject
git submodule add --branch develop --depth 1 
https://anton@bitbucket.org/anton/mysubmodule.git mysubmodule

Output:
