Use case or problem
To support various text editors, long lines of text are divided into multiple lines. To support GitHub-alike ability to create multiline paragraphs, the 2nd and later lines of such divided text are additionally indented.
For example, im creating a Vault with Readme which includes a section which says how to setup Obsidian. I expect that the Readme will be opened with Notepad.
