Because -20pt is less than 0pt, the lines will be indented at
the right side by 20pt.
The TeXbook, "Chapter 14: How TeX Breaks Paragraphs into Lines":
| The command `\hangindent=<dimen>' specifies a so-called hanging
| indentation, and the command `\hangafter=<number>' specifies the duration
| of that indentation. Let x and n be the respective values of \hangindent
| and \hangafter, and let h be the value of \hsize; then if n >= 0, hanging
| indentation will occur on lines n + 1, n + 2, ... of the paragraph, but if
| n < 0 it will occur on lines 1, 2, ... , |n|. Hanging indentation means

| x >= 0, the lines will be indented at the left margin, otherwise they will
| be indented at the right margin. For example, the "dangerous bend"
