I've just spot a missing translation in the italian docs and I guess that it's because I didn't understand it.
Can you tell me what is about?
Usage 2.3
max-markup-depth 1024 Maximum depth for the markup tree. If a markup has more levels, assume it will not terminate on its own, print a warning and return a null markup instead.
"Levels" refers to the number of nested blocks inside a markup block?
"Terminate"?
