excludes path handling

[Cactusbone]

I'm using windows, so path are not using / but \.
I can't seem to ignore a whole folder deep in the handled path
For example:

"excludes": [
        "node_modules/",
        "lib",
        "mocha.styl"
    ]

do work but not

    "excludes": [
        "node_modules/",
        "./views/css/lib",
        "./views/css/test/components/mocha.styl"
    ]
