EJS-lint hangs with invalid file path

[YZirkind]

Context: I'm running EJS-lint on Windows; Windows' path delimiter is a backwards-slash (e.g. C:\path\to\file.ext).

EJS-lint uses globby to generate a list of files from the paths provided as arguments. This is not mentioned in usage, nor in the Readme. Because globby doesn't support backward-slashes, when I pass in Windows path (e.g. views\index.ejs), it returns an empty array. So this:

EJS-Lint/cli.js

Line 33 in b5ee5a2

read(glob(argv._))

becomes:

    read([])

which never resolves, because read will then wait for stdin.

I would suggest documenting this, or using something like slash (by the developer of globby) to process the file paths before passing them into globby.

Good point, PR welcome to add slash.
