Can't find a way to have path-based sub-packages

[p0nce]

Story

In GFM examples, I've tried to have

 "dependencies": 
    {
        "gfm:sdl2": {"path": "../../", "version": "~master"}
    }

which is a handy way for code examples to be in sync with ~master.
As exemplified in dbox: https://github.com/d-gamedev-team/dbox/blob/master/examples/demo/dub.json#L43

Problem

DUB says:

Error executing command run: Path based dependency C:\Users\ponce\github\gfm\ is
 referenced with a wrong name: gfm:sdl2 vs. gfm

Now I'm not sure if this is possible with DUB design, so I'll add it's more a nice-to-have than a killer feature, since examples will realistically need to have versionned dependencies. It would just be more orthogonal.

Yes, that's definitely a bug. I'll look into it.
