Title: Supporting nested description

I suggest to use "closest describe".
Because I want to nested description as below.

* lib/tasks/foo.rake
```
namespace :foo do
task :bar => :environment do
end

task :baz => :environment do
end
end
```

* spec/tasks/foo_spec.rb
```
describe "foo" do
include_context "rake"

describe "foo:bar" do
it { subject.invoke }
end

describe "foo:baz" do
it { subject.invoke }
end
end
```
