• VSCode Version: 1.16.1
• OS Version: Windows 10 Version 1703 Build 15063.608

Steps to Reproduce:

1. Create launch.json with the following contents:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "typescript",
            "tsconfig": "tsconfig.json",
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

2. Run the build task
3. Produces: /usr/bin/bash: c:UsersrobertCodeNodegraphicsnode_modules.bintsc.cmd: command not found - (notice how all the directories are run together with no directory separator) in the console(I have the shell set to use git bash, rather than cmd.exe)

Reproduces without extensions: Yes
