Listing test

[Joe Horn]

If you use a Windows computer, you can type a non-breaking space in any text by holding down the Alt key while you type 0160 on the numeric keypad. These spaces don't get combined by web browsers, as the following example illustrates.

| | one
|  | two
|   | three
|    | four
|     | five

Tedious indeed, but   ...   it works, without the drawbacks of Code blocks.
