Lets a long text segment fit into the available layout width
Markdown has become the favored markup language to structure text files. With good cause: The Markdown syntax is very intuitive.
Sometimes we like to begin a new line without starting a whole new text block. Placing such a hard-line break gets complicated when hard-line wraps determine the line length inside the Markdown content files.
Sometimes we like to break a title or a line only for those layout versions, which show the text in full width.
Very long strings that are not hyphenated automatically may need an optional line break without a hyphen. We can generate the HTML tag with this replacement code.
