runme CLI fails on certain formats of markdown

[agardnerIT]

Not sure this is a bug or "as designed"...

I'm writing documentation with mkdocs material and one of the concepts available are snippets. Snippets are denoted with a special "scissor" syntax to include the given file:

--8<-- "include-me.md"

Broken Markdown

This markdown (starting with a snippet) produces no code blocks.

Note: I've added backspaces(\) just to keep GitHub issues formatting happy, they aren't there in the real doc.

--8<-- "snippets/live-code-snippets-button-executor.md"

## Import Dynatrace Dashboard

\``` {"name": "docker ps"}
docker ps
\```

Executing runme ls:

runme --filename docs/run-demo2.md ls --json
null

Side note: Shouldn't it return [] not null.

runme --filename docs/run-demo2.md ls returns textual no code snippets text.

Working Markdown

• Remove the scissor snippet line and runme ls works perfectly ✅
• Place the scissor snippet anywhere after the first title and runme ls works perfectly ✅

## Import Dynatrace Dashboard

\``` {"name": "docker ps"}
docker ps
\```

--8<-- "snippets/live-code-snippets-button-executor.md"

Shows:

runme --filename docs/run-demo2.md ls --json
[
  {
    "name": "docker ps",
    "file": "docs/run-demo2.md",
    "first_command": "docker ps",
    "description": "",
    "named": true,
    "run_all": true
  }
]
