[jeromesimeon]

Describe the bug

To Reproduce

In the following test, notice the end of the outer clause and the trailing ending clause as a text node.

bash-3.2$ cat test/data/nestedclause2.tem.md
{{#clause payment}}
Payment. As consideration in full for the rights granted herein, Licensee shall pay Licensor a one-time fee in the amount of "forty two" (42) upon execution of this Agreement, payable as follows: "wire transfer".
{{#clause foo}}
This clause is nested.
{{/clause}}
And contains more text.
{{/clause}}
bash-3.2$ markus transform --from markdown_cicero --to ciceromark --input test/data/nestedclause2.tem.md 
<-to ciceromark --input test/data/nestedclause2.tem.md
