[N0rbert]

Describe the bug
mdSilo modifies correct file and make it wrongly formatted.

To Reproduce
Create the following correct Markdown file in the shell:

mkdir /tmp/mdsilo
cat <<"EOF" > /tmp/mdsilo/file.md
# Simple Markdown document

Ordered list is below:

1. One
1. Two
1. Three

Unordered list is below:

* red;
* green;
* orange.

Bash script is below:

```bash
date
```

Two links in the list:

1. [`mdl`](https://rubygems.org/gems/mdl)
1. [`remark`](https://github.com/remarkjs/remark)

Two links in the text - [`mdl`](https://rubygems.org/gems/mdl), [remark](https://github.com/remarkjs/remark).

Third link - [file from `r4ds-exercise-solutions`](https://github.com/jrnold/r4ds-exercise-solutions/blob/master/.remarkrc).

Footnote is here [^fn1]

[^fn1]: the footnote text.

Some LaTeX text placed here intentionally for bookdown and xaringan:
\@ref(eq:do-no-touch-me), \eqref{binom_eq} and \@ref(exm:listing2-name).

Some text.
EOF

$ mdl file.md
$

and open this file using mdSilo to put some new characters at the last line and save it (for example replace Some text. with Some text at the end..
