I have set up a repository in Stash that has the default branch set to 'develop'. When I git clone this using the command line in Linux, I get the repository cloned with branch 'develop' set. When I try the same thing from SourceTree, I get the clone with branch 'master' set.
If I try the clone using the terminal to MINGW32, I get the master branch as well.
Is this a limitation of not being on the 1.9 git release?
