Wrong evaluation with bracket inside a tag

[Art4]

Hi,

I've found a bug while parsing a [ bracket inside a tag e.g. [b]:-[ [/b]. I've written 3 tests to specify the error. You can find them in this commit.

    public function testBracketInTag()
    {
        $this->assertProduces('[b]:-[[/b]', '<strong>:-[</strong>');
    }

    public function testBracketWithSpaceInTag()
    {
        $this->assertProduces('[b]:-[ [/b]', '<strong>:-[ </strong>');
    }

    public function testBracketWithTextInTag()
    {
        $this->assertProduces('[b]:-[ foobar[/b]', '<strong>:-[ foobar</strong>');
    }

As you can see the test testBracketInTag() works fine. The other tests testBracketWithSpaceInTag() and testBracketWithTextInTag() fails with something like <strong>:-[ /b]</strong>.

Here is the result of running the tests:

$ phpunit .

I haven't take a look in the code so far. Is there a chance for a quick bugfix?
