Fix nested list items

[rhysd]

Problem

At first, create file as follows:

- item
  - nested

And run markdown2confluence.

I expected

* item
** nested

but actually got

* item* nested

It looked broken.

Solution

So I fixed the renderer code handling the nested list by looking the head of each line in list items. Now it returns expected output.

Can we get this merged please?

Actually nevermind, this breaks a lot of other use cases. Fix should be done using listitem I believe.
