Let's confirm:

Code:

git clone -b development https://github.com/pilight/pilight.git pilight1
git clone -b development --single-branch https://github.com/pilight/pilight.git pilight2
git clone https://github.com/pilight/pilight.git pilight3
git clone --single-branch https://github.com/pilight/pilight.git pilight4
git clone -b master https://github.com/pilight/pilight.git pilight5
git clone -b master --single-branch https://github.com/pilight/pilight.git pilight6

1: 6091
2: 6091
3: 5772
4: 5385
5: 5772
6: 5365

Conclusion, -b makes --single-branch useless.
