The minimum style removes all the extra blank spaces and comments to have a compressed document.
There are a few comments that we may want to keep. To make a few
exceptions we can modify the default comment.
For instance if example.html is:
<!--Copyright: ML-->
<html>
<!--This comment is not copied in the min style-->
<br/>
<!--ML: My comment-->
content.
<!--JS: My name is John Smith-->
</html>
Then the output of
lexor example.html to html~min@comment="Copyright:"~
will be
<!--Copyright: ML--><html><br/> content. </html>
