Sublime Text has the option:

    // Set to "none" to turn off drawing white space, "selection" to draw only the
    // white space within the selection, and "all" to draw all white space
    "draw_white_space": "selection",

I would like to see selection added to list of possible values for editor.renderWhitespace. I find it incredibly useful.

While writing code, I prefer to not show whitespace. However, when I copy-paste code snippets, I like to know the whitespace matches the target document by simply selecting it (usually via Ctrl+A), not using the arrow keys or toggling a setting.

Thanks
