baseDir truncated when running coffee compiler with options 'coffee -co ../js ./

I used those directory structure in my projects:

     ./
    ├── js
    └── src
        ├── collections
        │   └── init.coffee
        ├── models
        │   └── init.coffee
        └── views
            └── init.coffee

I changed current directory to src and run coffee compiler with options `-co ../js ./`

And got truncated directories names:

    ./
    ├── js
    │   ├── dels
    │   │   └── init.js
    │   ├── ews
    │   │   └── init.js
    │   └── llections
    │       └── init.js
    └── src
        ├── collections
        │   └── init.coffee
        ├── models
        │   └── init.coffee
        └── views
            └── init.coffee

As I know *dot-slash* also (as is *dot*) used for reference to current directory.
