Using minimatch on Windows?

If I traverse a directory on Windows via `fs.readdir()` and `path.resolve()`, will minimatch work? Could you include the answer in the readme file? I don’t have a Windows machine, but am curious if my command line tool would work on one.

From the following interaction, I’d guess that the answer is “no”:

```
> mm('a\\b\\c.txt', 'a/**/*.txt')
false
```
