Expand description

Return the <seen amount of consecutive fenced code-block tokens> + 1 that occur within a fenced code-block events.

Use this function to obtain the correct value for code_block_token_count field of Options to assure that the enclosing code-blocks remain functional as such.

Returns None if events didn’t include any code-block, or the code-block didn’t contain a nested block. In that case, the correct amount of fenced code-block tokens is DEFAULT_CODE_BLOCK_TOKEN_COUNT.
