Prompt written on Linux or macOS has black background

Originally reported by @joeyaiello, and I've seen it too on macOS:

Need to keep using the existing Console.BackgroundColor instead of changing it to black.

With VS Code 1.12.0 you can work around this issue by adding the following to settings.json:

"workbench.colorCustomizations": {
    "terminal.ansiBlack": "#1E1E1E"
}

This is for Dark+, replace 1E1E1E with the appropriate color for your theme.
