The cwd option is specified in the docs here.

However, It doesn't appear to be used anywhere in the picomatch source code. See this github text search. https://github.com/micromatch/picomatch/search?q=cwd

Here are some simple tests proving the cwd option isn't used.

var picomatch = require('picomatch');

console.log(
    picomatch.isMatch('file.txt', '*.txt')
); //true

console.log(
    picomatch.isMatch('C:/projects/file.txt', '*.txt', { cwd: 'C:/projects' })
); //false

console.log(
    picomatch.isMatch('file.txt', '*.txt', { cwd: 'totally/bogus/cwd' })
); //true

Does picomatch need to be updated to add the cwd option, or should all the unsupported options in the docs be removed?
