Extra paragraphs incorrectly spawning when ":end:" appears.

[Tom Alexander]

This test document has 1 paragraph:

```

foo

bar

baz

```

which parses as:

```

(section

  (paragraph "foo\nbar\nbaz\n")

)

```

This test document should have 1 paragraph but org-mode is parsing it as 2:

```

foo

:end:

baz

```

which parses as:

```

(section

  (paragraph "foo\n")

  (paragraph ":end:\nbaz\n")

)

```

The paragraph documentation[1] states that:

> Empty lines and other elements end paragraphs.

But the document contains no empty lines and we can see in the output that it only contains paragraphs.
