Free text paragraphs seem to be the default mode in Markua. I am still wondering if there could be errors while parsing a Markua file, or if we don't recognize something as a special tag, then it should be considered as a paragraph.

We are not there yet, but for example including a file looks like this:

![title](path/to/file.pl)

What if we have line like this:

![title](path/to/file.pl

That is, the closing parentheses is missing. Should we report this as a parsing error or consider this as a paragraph?

For now, I think, everything that is not exactly recognizable as some Markua code will be considered a paragraph.

So let's implement this now.
