[FEATURE] Hierachical depth limit

[pale3]

E.g checkout url:

https://redmine/project/subproject/subsubproject/foo.git

Stored on disk:

repositories/
└── project/
    └── subproject/
        └── subsubproject/
            └── foo.git

Would it be possible in hierarchical style to invent depth. So for ^above when limiting it to "Depth 1" will store foo.git within parent called "subsubproject".

When Depth 1 = true

checkout url:

https://redmine/subsubproject/foo.git

repositories/
└── subsubproject/
       └── foo.git
