Currently only gitignores from cwd and down are taken into account for gitignore filtering. What about those who are higher in a hierarchy?

Use case: monorepo repositories (like babel f

Please describe the minimum necessary steps to reproduce this issue:

The example given in README for API some is not working as intended.
Link to example in REPL

const mm = require('micromatch');
// mm.some(list, patterns[, options]);

console.log(mm.some(['foo.js', 'bar.js'], ['*.js', '!foo.js']));
// true
console.log(mm.so

node-glob has the nonull option which instead of returning an empty array if no patterns matches, it returns the patterns that didn't match anything. This can be useful when you want to report to the user what patterns/filepaths couldn't be found.

Definitely needs a better name than nonull though.

Make the test code a but smarter and less verbose

Similar to micromatch/glob-base#5

One test fails,

  1) should get a base path: qmarks::

      AssertionError: '?' == '.'
      + expected - actual

      -?
