- [x] foo
  - [ ] bar
  - [X] baz
- [ ] bim

* [x] foo
* [X] bar
* [ ] baz

This works for ordered lists too:

1. [x] foo
2. [X] bar
3. [ ] baz

Some examples which should not match:

 - Checkbox [x] in the middle
 - Checkbox at the end [ ]
 - [  ] too many spaces
 - **[x] Checkbox inside of emphasis**
 - No text, as shown in these examples:
   - [x]
   - [ ]
   -    [x]
   -           [x]

Here's a test using `<del>`:

 - [x] <del>Checkbox inside of strikeout</del>

And another which does not render the checkbox:

 - <del>[x] Checkbox inside of strikeout</del>
